            A Catalog of Available X.500 Implementations

Status of this Memo

  This memo provides information for the Internet community.  It does
  not specify an Internet standard.  Distribution of this memo is
  unlimited.

Abstract

  The goal of this document is to provide information regarding the
  availability and capability of implementations of X.500.  Comments
  and critiques of this document, and new or updated descriptions of
  X.500 implementations are welcome.  Send them to the Directory
  Information Services Infrastructure (DISI) Working Group
  ([email protected]) or to the editors.

1.  Introduction

  This document catalogs currently available implementations of X.500,
  including commercial products and openly available offerings.  It
  contains descriptions of Directory System Agents (DSA), Directory
  User Agents (DUA), and DUA client applications.  The latter can
  include such applications as browsers, DSA management tools, or
  lightweight DUAs that employ an application-level protocol to
  communicate with a DUA (which then in turn communicates with a DSA)
  to support user service.  Section 2 of this document contains a
  listing of implementations cross referenced by keyword.  This list
  will aid in identifying particular implementations that meet your
  criteria.

  To compile this catalog, the DISI Working Group solicited input from
  the X.500 community by surveying several Internet mailing lists,
  including: [email protected], [email protected], [email protected],
  and [email protected].

  Readers are encouraged to submit comments regarding both the form and
  content  of  this  memo.  New submissions are always welcome.  Please
  direct input to the parties as described in the Status of  this  Memo
  section.  DISI will produce new versions of this document when a suf-
  ficient number of changes have been received.  This  will  be  deter-
  mined subjectively by the DISI chairperson.

1.1  Purpose

  The growth of existing X.500 pilot activities (e.g., White Pages
  Pilot Project) and the advent of new pilots (e.g., ARRNet Directory
  Services Project, NIST/GSA Pilot Project) are signals that X.500 is a
  viable directory service mechanism for the Internet community.  A
  goal of DISI is to enable the continued growth of X.500 by lowering
  the lack-of-information barrier.  This document takes one step toward
  that goal by providing an easily accessible source of information on
  X.500 implementations.

1.2  Scope

  This document contains descriptions of either commercially or freely
  available X.500 implementations.  It does not provide instructions on
  how to install, run, or manage these implementations.  Because the
  needs and computing environments of each organization differ vastly,
  no recommendations are given.  The descriptions and indices are
  provided to make the readers aware of existing options and to enable
  more informed choices.

1.3 Disclaimer

  Implementation descriptions were written by implementors and vendors,
  and not by the members of DISI.  Although DISI has worked with the
  description authors to ensure readability, no guarantees can be made
  regarding the validity of descriptions or the value of said
  implementations.  Caveat emptor.

1.4  Overview

  Section 1 contains introductory information.

  Section 2 contains a list of keywords, their definitions, and a cross
  reference of the X.500 implementations by these keywords.

  Section 3 contains the X.500 implementation descriptions.

  Section 4 lists the editors' addresses.

1.5  Acknowledgments

  The creation of this catalog would not have been possible without the
  efforts of the description authors and the members of the DISI
  Working Group.  The editors thank you for your hard work and
  constructive feedback.  A special thanks is also extended to the
  members of the NOCTools Working Group.  The "Network Management Tool
  Catalog" (RFC-1147) served as a valuable example.  Bob Stine and Bob
  Enger made key suggestions that enabled us to learn from their
  experiences.

  The efforts of the editors were sponsored by Defense Advanced
  Research Projects Agency Contract Number DACA76-89-D-0002 (Field
  Operational X.500 Project), and U. S. Department of Energy Contract
  Number DE-AC03-76SF00098.

2.  Keywords

  Keywords are abbreviated attributes of the X.500 implementations.
  The list of keywords defined below was derived from the
  implementation descriptions themselves.  Implementations were indexed
  by a keyword either as a result of: 1) explicit, not implied,
  reference to a particular capability in the implementation
  description text, or 2) input from the implementation description
  author(s).

2.1  Keyword Definitions

  This section contains keyword definitions.  They have been organized
  and grouped by functional category.  The definitions are ordered
  first alphabetically by keyword category, and second alphabetically
  by implementation name within keyword category.

  The index is organized as follows: keywords appear in alphabetical
  order; implementations characterized by that keyword are listed
  alphabetically as well.  Note that a "*" is used to indicate that the
  particular implementation, or feature of the implementation, may not
  be available at this time.

  For formatting purposes, we have used the following abbreviations for
  implementation names: UWisc (University of Wisconsin), HP X.500 DDS
  (HP X.500 Distributed Directory Software), IS X.500 DSA/DSAM,
  DUA(Interactive Systems' X.500 DSA/DSAM, DUA).

ABSTRACT

  Alliance OSI includes XDS (API), DUA, DSA and DIB all as separate
  components.

  Touch's X.500 products have been designed for complete portability to
  any operating system or hardware environment.  The protocols include
  DAP and DSP of the OSI X.500 specification along with the required
  XDS, DUA, DSA and DIB components.  In addition to X.500, Touch sup-
  plies other OSI protocol layers including: ROSE, ACSE, Presentation,
  Session and any of the OSI lower layers (Transport, Network along
  with RFC-1006).  Touch also supplies other application layer proto-
  cols such as X.400, FTAM, CMIP (and general network management), etc.

  The Alliance OSI X.500 is compliant with the CCITT X.500 1988 Recom-
  mendations. The ROSE/ACSE/Presentation/Session stack can be option-
  ally provided by Touch.

  The DUA may represent a single user, or may represent a group of
  users.  It may be attached to a given DSA within the same system but
  is also capable of invoking operations in Touch's or any other
  vendor's compliant DSA on a remote system.  The binding operation
  requires the user to give a distinguished name and password in order
  for the Directory to identify the user.  Once an association is esta-
  blished the user may invoke the following operations: READ, COMPARE,
  ABANDON, LIST, SEARCH, ADD_ENTRY, REMOVE_ENTRY, MODIFY_ENTRY,
  MODIFY_RDN.

RFC 1292                   Alliance OSI X.500               January 1992


  Due to the fact that access to the physical disk is in most  cases  a
  blocking  operation  (synchronous)  Touch  has separated the database
  processing (I/O process) from the DSA protocol entity.  This  separa-
  tion allows the DSA entity to continue processing during the frequent
  database accesses from the DSA. The DSA supports  all  the  Directory
  operations  as specified in the CCITT X.500 specification.  Chaining,
  Referral and Multicasting are provided and supported in the  Alliance
  OSI  DSA.   The DSA supports all the service control options included
  in the operation command arguments.  Filtering  conditions  are  sup-
  ported via the FILTER in the SEARCH operation.

  The Alliance OSI X.500 product supports all the NIST defined manda-
  tory X.500 and X.400 object classes and attributes.

  Alliance OSI X.500 supports all the mandatory Directory attribute
  types (and their associated abstract syntaxes) in the NIST Directory
  implementation profile. Touch has extended the Directory and allows
  users to define private attributes.  This means that a user can util-
  ize the Alliance OSI Directory for a general purpose, user defined
  database activity.

  Touch provides a full set of administration and Directory management
  facilities.

  Touch is in the process of integrating the X.500 product with the
  Worldtalk 400 product. Worldtalk 400 is Touch's end user X.400 mes-
  sage switch, providing gateways between proprietary mail systems
  (SMTP, Microsoft Mail, MHS, cc:mail, etc.) and X.400.  X.500 is a key
  component for a messaging network.

COMPLETENESS

  Strong Authentication is not supported however Simple Authentication
  is supported.

INTEROPERABILITY

  No interoperability testing has been completed as of yet.

PILOT CONNECTIVITY

  Numerous OEMs are using the Alliance OSI X.500 product in product
  development as well as in pilot networks.

CAVEATS AND GENERAL LIMITATIONS

  Currently the Alliance OSI X.500 DIB has only been validated within a
  UNIX File System.  The protocol components are portable as is the
  interface between the DSA and the DIB.

INTERNETWORKING ENVIRONMENT

  Alliance OSI X.500 can be utilized over TCP/IP and/or OSI Transport
  on LANs and WANs.  Currently X.500 has only been verified over OSI,
  however other Alliance OSI application layers have been configured
  over a RFC-1006 which is available as part of the Alliance OSI pro-
  duct line.

HARDWARE PLATFORMS

  Alliance OSI has been ported to numerous platforms ranging from IBM
  Mainframes MVS to Apple Macintosh.  For UNIX environments Touch has
  portations for 386 AT/Bus, SUN-3 and 4, Mips, and HP.

SOFTWARE PLATFORMS

  As stated above, the Alliance OSI product have been ported to
  numerous systems.  In the UNIX environment the X.500 product exists
  on SUN OS 4.0 and greater, Mips RISC OS, Interactive 386 and HP-UX.

ABSTRACT

  The implementation consists of a set DUA library routines, a terminal
  interface, and a DSA. The implementation was developed in C on Sun 3
  workstations under the UNIX operating system. All underlying services
  are provided by the ISODE development package. The development pack-
  age is also used for encoding and decoding ASN.1 data as well as for
  other data manipulation services. Using the ISODE package the imple-
  mentation can be run over both OSI and TCP/IP protocols.

  The DSA provides full support for both DAP and DSP protocols, confor-
  mant with ISO 9594/CCITT X.500 standards. The DIB is maintained using
  a locally developed relational database system. The interface to the
  database system consists of a set of SQL-like C functions.  These are
  designed to allow straightforward replacement of the local database
  system with a more powerful commercial system. To achieve better per-
  formance several options are supported that permit loading of
  selected portions of the database into core. When these options are
  selected data can be retrieved more quickly from in-core tables; all
  modifications to the DIB are directly reflected in the in-core tables
  and the database.

COMPLETENESS

  To date the Read, Compare, List, Add Entry, and Remove Entry opera-
  tions have been implemented and are supported over both DAP and DSP;
  aliasing and replication are also supported.  The version under
  current development (available January '92) includes simple authenti-
  cation, access control, and the Search operation. The modify opera-
  tions and Abandon are not supported and there is no support for
  schema checking.

RFC 1292                         Custos                     January 1992


INTEROPERABILITY

  Have successfully interoperated with QUIPU and OSIWARE over the DAP.
  No DSP interoperability testing has been done.

PILOT CONNECTIVITY

  Not tested.

BUGS

  Some testing in the near term future will be done to try to identify
  these, but presently it's not possible to give an accurate list of
  bugs.

CAVEATS AND GENERAL LIMITATIONS

  No limitations on file sizes, etc. The only side effects to creating
  large files should be in the area of performance. Specifically,
  optimization requires loading parts of the DIB in core so greater
  memory requirements will be necessary for achieving better perfor-
  mance with a large database.  Any platform the implementation can be
  ported to (generally any platform ISODE can be ported to) should sup-
  port all features.

INTERNETWORKING ENVIRONMENT

  RFC-1006; TP4/CLNP (SunLink OSI) over 802 and X.25 (SunLink X.25).

HARDWARE PLATFORMS

  It has been run on Sun-3, but there are no known reasons why it
  should not run on any hardware running the ISODE software.

SOFTWARE PLATFORMS

  It requires UNIX and the ISODE software package.  It's been developed
  and tested with ISODE version 6.0 and Sun OS version 4.1.1.  Uses a
  locally developed relational DBMS that should be easily replaceable
  with commercially available relational systems.

AVAILABILITY

  While under continuing development, availability of the implementa-
  tion is limited to organizations making appropriate arrangements with
  NIST.  The implementation will be publicly available when development
  is completed.

ABSTRACT

  DCE/GDS (Distributed Computing Environment/Global Directory Service)
  was based on the original Siemens DIR.X product. It supports full DUA
  and DSA functions for globally unique identifications and for loca-
  tion of objects in the network. It also provides functions to answer
  queries (both yellow-page and white-page) about objects and attribute
  information.  The software implements full DAP and DSP protocols
  specified in X.519.  An ASN.1 compiler and required ACSE, ROSE,
  presentation, session and RFC-1006 protocols implementations are also
  included.

  The product has been successfully participated in X.500 Cebit Intero-
  perability tests at 1990 and 1991 Hanover Fairs. It also intero-
  perates with the ISODE QUIPU X.500 implementation.

COMPLETENESS

  Compliant with EWOS Agreements which is being harmonized with OIW
  Agreements.

  Strong authentication in X.509 is not yet implemented. (Password
  scheme is currently used.)

  Consists of both DUA and DSA implementation according to the 88 CCITT
  X.500 and ISO 9594 standard.  The X/Open standard XDS (version 1.0)
  and XOM (version 2.0) interface libraries are also provided.  XDS and
  XOM interfaces are also used to access DCE/CDS (Local Cell Directory
  Service) transparently. A GDA (Global Directory Agent) serves as the
  gateway between the DCE CDS and GDS.

ABSTRACT

  DE (Directory Enquiries) is intended to be a simple-to-use interface,
  suitable for the naive user, and suitable for running as a public
  access dua to provide lowest common denominator access to the Direc-
  tory.  It is a scrolling interface and will thus run on dumb termi-
  nals, even teletypes!  The user is asked to fill in up to 4 questions
  per query: person's name; department; organization; country.  The
  prompts are very verbose -- the intention is that the user should not
  be able get stuck, and information on how to get into the help system
  should always be on the screen.  The help screens (of which there are
  15) are aimed at the non-technical user.  Whilst the outwards appear-
  ance of the interface is simple, a lot of attention has being given
  to mapping the strings the user enters onto X.500 operations in such
  a way that the interface seems to do the "right thing".  An important
  characteristic is the way the interface tries a series of searches,
  gradually relaxing the matching criteria from exact (in some sense),
  to good, through to "fuzzy".  A considerable amount of configuration
  is possible to present the results in locally acceptable formats.

  DE was funded by the COSINE PARADISE project, and DE is used as the
  PARADISE public access dua.  You can test the software by telnet to
  128.86.8.56 and logging in as dua -- no password required.

COMPLETENESS

  The interface is a querying engine only.

INTEROPERABILITY

  DE is built with the ISODE software (release 7.0).  Its interopera-
  bility relies on the correctness of the Quipu libraries.

RFC 1292                           DE                       January 1992


PILOT CONNECTIVITY

  The interface is in use as the COSINE Central DUA Service, and is
  used by a number of UK institutions as a public access dua (usually
  over X.29).  It is able to query entries in pilots throughout the
  world.  It is not able to query for entries which are in organiza-
  tions beneath locality entries under country entries.  It is not pos-
  sible to query for people who do not work for organizations.  The
  interface only searches for entries of the following type: organiza-
  tions, organizational units, people, roles, and rooms.

BUGS

  Send bug reports to:

          [email protected]
          [email protected]

CAVEATS AND GENERAL LIMITATIONS

  DE tries to cater well for the general case, at the expense of not
  dealing with the less typical.  The main manifestation of this is
  that the current version will not query under localities immediately
  under the country level.

  It is not possible to display photographs or reproduce sound attri-
  butes.

INTERNETWORKING ENVIRONMENT

  Same as ISODE.  ISODE supports TCP/IP, TP0, and X.25.

HARDWARE PLATFORMS

  Should be the same as ISODE in general.

SOFTWARE PLATFORMS

  DE requires the ISODE (current release 7.0) libraries.

AVAILABILITY

  DE is openly available as part of ISODE and as part of the COSINE DUA
  package.   Available by FTAM and FTP, source code freely available.

ABSTRACT

  The DIXIE protocol is used to give X.500 access to platforms that
  have only TCP/IP access.  The DIXIE server is an intermediate proto-
  col server that communicates with Internet clients on one side using
  a text-based UDP/TCP protocol and an X.500 DSA on the other side
  using DAP.  The protocol is fully described in RFC 1246.  A subset of
  the X.500 DAP is exported to the clients through the DIXIE protocol.
  There is a DIXIE API provided in the form of a library of C-callable
  routines.

  The DIXIE protocol and server are being used by the following
  products/projects:

    UD, a simple command line white pages DUA for Unix machines (dis-
    tributed with the DIXIE server)

    maX.500, a white pages DUA for the Macintosh (available from the
    same place as the DIXIE server)

    Network monitoring of DSAs by our Network Operations Center

    Lookup and display of caller identification based on telephone
    caller ID (using ISDN).

COMPLETENESS

  The DIXIE protocol does not support access to all X.500 features and
  operations.  All DAP operations except Abandon are supported.  Gen-
  eral searches (including multiple component searches) are supported.
  The DIXIE protocol supports none and simple authentication.  A subset
  of the service controls are supported.

RFC 1292                         DIXIE                      January 1992


INTEROPERABILITY

  The current implementation of the DIXIE server works with the QUIPU
  DSA and DAP library.

PILOT CONNECTIVITY

  The DIXIE server has been tested in the Internet and PARADISE pilots.
  It provides full DUA Connectivity subject to the limitations dis-
  cussed above under completeness.

BUGS

  There are no known outstanding bugs.  But reports should be sent to
  [email protected].

CAVEATS AND GENERAL LIMITATIONS

  None, aside from those mentioned above under completeness.

INTERNETWORKING ENVIRONMENT

  DIXIE clients use TCP or UDP to communicate with the DIXIE server.
  The DIXIE server uses RFC-1006 with TCP/IP to communicate with the
  DSA, though other transport mechanisms for DSA communication should
  be possible.

HARDWARE PLATFORMS

  The DIXIE server is known to run on Sun 3, Sun 4, and DEC 3100 plat-
  forms.  It should run on any UNIX platform.  The DIXIE library is
  known to run on the same platforms, and also on the Macintosh.

SOFTWARE PLATFORMS

  The DIXIE server and library is known to run under SunOS 3.5, SunOS
  4.1.1, Ultrix 4.1 and 4.2.  The DIXIE library also runs on the Macin-
  tosh System Software 6 or later.

AVAILABILITY

  This software is openly available.  It may be obtained by anonymous
  FTP from terminator.cc.umich.edu in the directory ~ftp/x500. Documen-
  tation on the DIXIE protocol is provided along with the source code,
  which includes source for the DIXIE server, DIXIE library, and the UD
  client.

ABSTRACT

  DS-520 X.500 Distributed Directory Services for UNIX System V and
  DS-521 X.500 Directory User Agent (DUA) for UNIX System V form an
  integral part of the Retix OSI Networking Products family.  Designed
  for systems vendors, public carriers, and other OEMs, DS-520 is a
  complete high-performance implementation of X.500 in source code
  form, including a DUA, DSA Manager (DSAM), and DSA.  DS-521
  represents a subset of this product offering. It provides the DUA
  portal into the directory, which, for example, meets the needs of
  software vendors who plan to provide application packages with X.500
  Directory interaction capabilities. Within these two offerings, the
  DUA possesses two forms of interface. The first form, the DUA with
  User Interface, provides an interactive character-based user inter-
  face for users of Directory services.  The user agent provides access
  to the Directory via basic Directory service requests. The second
  form, the DUA with Programmatic Interface provides a standardized
  programmatic interface to application programs that must access
  Directory information. The interface is conformant to the X/Open
  Object Management (XOM) and X/Open Directory Services (XDS) stan-
  dards. This component provides all functionality related to Directory
  access and general OSI services down to the session layer. The DSAM
  provides an interactive character oriented user interface to a Direc-
  tory administrator.  The DSAM provides management functions either
  local to or remote from a DSA. Both the DUA and the DSAM are useful
  in the training, management, and manipulation of Directory entries
  maintaining operational and user attribute information. The DSA main-
  tains Directory database information and provides users the ability
  to read/compare, modify, search, and manage entries within the data-
  base. It maintains all or fragments of the Directory Information Base
  (DIB) and provides abstract service ports for DUAs and DSAs over DAP
  and DSP protocols respectively.

RFC 1292                     DS-520, DS-521                 January 1992


COMPLETENESS

  DS-520 represents a complete implementation of the 1988 X.500 Recom-
  mendations with the exception of strong authentication as outlined in
  X.509. It is conformant to NIST, EWOS, and UK GOSIP Directory pro-
  files. It provides session through application layer protocol support
  and hence incorporates ROSE, ACSE, Presentation, and Session within
  its product stack. In addition to including all the attribute types,
  syntaxes, and object classes defined in X.520 and X.521, the DS-520
  includes support for those specified in the 1988 X.400 Recommendation
  X.402, Annex A. Remote on-line management of the DSA is supported by
  means of Network Management Forum CMIP.

  DS-521 represents a complete implementation of the X/Open Object
  Management (OM) and X/Open Directory Services (XDS) standards. It
  also incorporates session through application layer protocol support
  and thus includes ROSE, ACSE, Presentation, and Session within its
  product stack.

INTEROPERABILITY

  The DS-520 has been tested to interoperate with Banyan (DAP), CDC
  (DSP), IBM, ICL, OSIWare, Nixdorff, Unisys (DSP), Wollongong (DAP),
  and 3-Com (DSP).

  The DS-521 subset has undergone no separate interoperability testing.

PILOT CONNECTIVITY

  DSA Connectivity provided by the DS-520: The DSA provides complete
  support for the X.511 Abstract Service Definition, the directoryAc-
  cessAC and the directorySystemAC defined in the X.519 Protocol
  Specifications, and the Distributed Directory defined in the X.518
  Procedures for the Distributed Directory. It supports all the object
  classes, attribute types, and attribute syntaxes defined in X.520 and
  X.521. It does not support the Internet DSP however.

  DUA Connectivity provided by both the DS-520 and DS-521: The DUA pro-
  vides complete support for the X.511 Abstract Service Definition and
  the directoryAccessAC defined in the X.519 Protocol Specifications.
  The DUA with User Interface supports only a subset of the X.500
  attributes and object classes defined in X.520 and X.521. The DUA
  with Programmatic Interface, however, does support all the object
  classes, attribute types, and attribute syntaxes defined in these two
  recommendations.

BUGS

  Product Action Requests (PARs) stemming externally from customers and
  internally from customer service and quality assurance engineers are
  generated and published in the form of weekly reports. A description
  and status of these PARs are provided to customers possessing
  software maintenance agreements.

CAVEATS AND GENERAL LIMITATIONS

  DS-520 and DS-521 are source code products ported to UNIX System V
  Release 3 and 4. Makefiles to generate the system are provided for
  the AT&T System V, SCO, and Interactive UNIX systems.

INTERNETWORKING ENVIRONMENT

  DS-520 and DS-521 offer two main compile time configuration options
  and hence internetworking configurations. In the first of these, they
  interface to the UNIX System V Transport Library Interface (TLI).
  The TLI provides a path between the session layer of a UNIX OSI
  application process and an OSI transport provider installed in the
  UNIX kernel. The latter transport provider may take the form of a
  Retix Unix LAN (LT-610) or WAN (WT-325) transport product. The second
  main option utilizes the UNIX System V ACSE/Presentation Library
  interface (APLI and the A/P Library), which provides OSI ACSE and
  Presentation layer services. The Retix AP-240 Presentation syntax
  manager product serves to map the standard Retix Presentation layer
  interface to the AT&T APLI. The APLI upper layers services may be
  provided by the Retix UL-220 product. UL-220 is the Retix implementa-
  tion of the AT&T Open Networking Platform Upper Layer Services module
  and includes the A/P library, as well as the OSI ACSE, Presentation,
  and Session services.

  DS-520 and DS-521 may also run on top of the TCP/IP stack by means of
  the Retix MP-120 product. MP-120 is a STREAMS based driver that
  implements RFC-1006 and thus allows OSI applications to run over a
  network based on the Internet suite of protocols (TCP/IP). Its main
  function provides a conversion between the TCP stream to the data
  packets required by OSI Transport Class 0 protocol and vice versa. As
  part of this process, it converts TCP/IP 32-bit addresses to hex
  values for use with OSI applications.

HARDWARE PLATFORMS

  Being source code products ported to the UNIX System V Release 3  and
  4  operating system environment, DS-520 and DS-521 are hardware plat-
  form independent. They currently both have sample portations and test
  configurations on various Intel 80386 platforms running Unix System V
  Release 3 and 4.

SOFTWARE PLATFORMS

  Currently, DS-520 and DS-521 include reference implementations for
  the AT&T System V Release 4, SCO UNIX System V/386 Version 3.2.2, and
  the Interactive UNIX System V/386 Version 2.2 operating systems.
  Raima Corporation's db_Vista III Version 3.1 serves as the database
  engine for the Directory product.

ABSTRACT

  HP's Distributed Directory Software is a fully distributed Directory
  that supports both the DAP and DSP protocols, which were specified in
  the 1988 CCITT/ISO X.500 documents.  Besides implementing the stan-
  dard, we have also put in proprietary access control and replication.
  These additional features will be migrated to the standard definition
  at the time that they are stable.  Users are able to define their own
  attributes, objects classes and DIT structure rules.

  In order to make this software easy to use a set of menu driven
  screens have been provided.  There are easy to use data access and
  data management screens.  For system administrators, these is also a
  set for screens that are used to help configure the servers and
  manage the schema. Startup and Shutdown utilities are also included.

  For application developers an X/Open-APIA XDS API is provided, along
  with some helper routines that help reduce development time.  The XDS
  API includes the following functions:

          Bind
          Read
          Search
          Add
          Remove
          Unbind
          Version

  A subset of the X/Open-APIA Object Management (XOM) functions are
  available thru the interface.  The subset are those that are neces-
  sary to perform the directory operations.

  For bulk operations a batch interface is also available.

ABSTRACT

  maX.500 is a Macintosh X.500 directory application useful for
  displaying and modifying white pages information about people.  It
  runs on top of the DIXIE protocol (described in RFC 1246).  maX.500
  is currently in production release 1.1 within the University of
  Michigan and several other places.

  Features include the ability to display and modify the following
  attributes: title, description, commonName, uid, mail, postalAddress,
  homePostalAddress, telephoneNumber, facsimileTelephoneNumber, home-
  Phone.  Photos can also be displayed.  The software also provides
  access to the finger protocol.  Various preferences are user-
  tailorable, including caching.

COMPLETENESS

  maX.500 uses the DIXIE protocol to access X.500 and thus is subject
  to the same completeness restrictions as DIXIE.  It provides Read,
  Search, and Modify capabilities.

INTEROPERABILITY

  Works with the DIXIE server, which works with the QUIPU DSA and DAP
  library.

PILOT CONNECTIVITY

  It has been tested (in conjunction with the DIXIE server) in both the
  Internet and PARADISE pilots.

BUGS

  No outstanding bugs are known.  But reports should be sent to

ABSTRACT

  OSI-DSA provides a Directory System agent for controlled access to
  the OSI Directory Information Base.  It provides full support for the
  joint ISO/IEC IS-9594 International standard and CCITT X.500 Recom-
  mendations 1988 protocols necessary for implementing the Directory
  Information Base distributed across a number of DSA's.

  The product also includes an Administration User interface program,
  to allow a human administrator to construct and maintain the local
  Directory Information.

  Specific features provided by the Directory System Agent include:

      (i)    Support of the directoryAccessAC and directorySystemAC
             application contexts (i.e. both Directory Access Protocol
             (DAP) and Directory System Protocol (DSP)

      (ii)   Bind Security levels of none and simple unprotected.

      (iii)  Capability of acting as a first level DSA.

      (iv)   Support for chaining and multi-casting where necessary in
             handling distributed operations. Also supports the return
             of referrals.

      (v)    Support for all attribute types and syntaxes defined in
             X.520.  Users are also able to define their own attributes
             and syntaxes.

      (vi)   Support for all the object classes and attribute sets
             defined in X.521.  Users are also able to define their own
             object classes and attribute sets.  Support is also pro-
             vided for a NAME-BINDING specification, for defining the

             Directory Information Tree (DIT) structure.

      (vii)  An access control mechanism based on the ISO  access  con-
             trol  working  papers  to  allow for controlled access and
             maintenance of Directory entries and attributes.

      (viii) Logging of errors and significant Directory events, as
             well as optional trace information.

      (ix)   The OSI-DSA utilizes the services of ROSE (X.219) and ACSE
             (X.217) as defined in clause 8 of X.519

  The Administration program provides the following functions

      (i)    An interface to each of the basic Directory Operations of
             Read, Compare, List, Search, Add, Modify, ModifyRDN.

      (ii)   A Dump/Load utility to dump the information in the local
             DIB into an ASCII file and load it again into the DIB from
             such a file.

      (iii)  Knowledge Reference maintenance facilities to Add, Delete
             Modify and Read all types of Knowledge References.

      (iv)   Facilities to control the operation of local Directory
             processes.

      (v)    Control over the level of logging and tracing.

COMPLETENESS

  The OSI-DSA provides all functionality defined in, and is fully con-
  formant to, the joint ISO/IEC IS-9594 International standard and
  CCITT X.500 Recommendations 1988, and the NIST 1988 Stable agreements
  on Directory Services.

  The only exception is that no support is provided for strong authen-
  tication or digital signatures.

  Conformance with respect to clause 9 of X.519:

      (i)    The DSA supports both the directoryAccessAC and directo-
             rySystemAC application contexts.

      (ii)   The DSA is capable of acting as a first-level DSA.

      (iii)  The chained mode of operation as defined in X.518 is sup-
             ported.

             Directory Information Tree (DIT) structure.

      (vii)  The DSA conforms to all the static requirements defined in
             clause 9.2.2 of X.519

      (viii) The DSA conforms to all the dynamic requirements defined
             in clause 9.2.3 of X.519

INTEROPERABILITY

  The product was demonstrated at "Interop 91" in San Jose, October
  1991 as part of the OSI Showcase demo involving several vendors'
  directory products.

  Informal interoperability has been achieved against the ISODE 6.0
  QUIPU Directory implementation.  Interoperability testing against
  other vendors is in progress.

  Formal interoperability testing is awaiting the soon to be completed
  OSInet X.500 interoperability test suite.

PILOT CONNECTIVITY

  Not tested.

BUGS

  Full customer support is provided via your local Unisys Customer Ser-
  vices Organization.

CAVEATS AND GENERAL LIMITATIONS

  Results returned via the OSI-DSA are presently limited to 32K in the
  current release, which is in line with the 1988 NIST agreements.

  Patches for the Unix V.4 release may be made available on request to
  raise this limit to 1Mb.

  The product currently does not provide any support for replication,
  although development work is in progress, based on the current ISO
  Draft proposal for Replication.

INTERNETWORKING ENVIRONMENT

  OSI-DSA runs over all communications environments supported by the
  Unisys OSI stack product (see Software platforms). Currently these
  support TP0, TP2, TP3 and TP4 over X.25 and TP4 over CLNP on 802.3
  and X.25.  Support for RFC1006 over TCP/IP is under development.

HARDWARE PLATFORMS

  The product is available on all Unisys Unix 6000 Series machines.

  Source code is available for portation to non-Unisys platforms.

SOFTWARE PLATFORMS

  The product is distributed and supported for Unix System V.3 and Unix
  System V.4.

  On Unix V.3, it requires the Unisys Application Presentation Service
  OSI stack software (APS), and Unisys Transport Network Service
  software (TNS).  On Unix V.4, it requires the integrated Unisys OSI
  stack software product (STK).  These services are accessed via the
  ROSLI (ROSE) and APLI (ACSE) programming interfaces which are
  currently the subject of standardization efforts by XOpen and Unix
  International.

  A runtime version of either the Informix or Oracle relational data-
  base products is required for the Directory Information Base.

ABSTRACT

  OSI-DUA is a Unix C Program interface library. It allows OSI or user
  applications to access the services of an X.500 conformant Directory,
  by making calls to a library of C routines.

  Specific features provided by this program interface library are as
  follows:

      (i)    Connection to any remote X.500 conformant DSA via an OSI
             stack, or connection to a co-resident Unisys OSI DSA via
             IPC mechanisms.

      (ii)   All operations defined in the directoryAccessAC applica-
             tion context (Bind, UnBind, Read, Compare, Search, List,
             AddEntry, ModifyEntry, ModifyRDN, Abandon, DeleteEntry).

      (iii)  Directory Bind security levels of none and simple unpro-
             tected.

      (iv)   Execution of both blocking and non-blocking operations.
             (A non-blocking call to the library will return immedi-
             ately, allowing for results to be obtained once the opera-
             tion has completed)

      (v)    Acceptance of multiple concurrent non-blocked operations
             on the one user session.

      (vi)   The DUA utilizes the services of ROSE (X.219) and ACSE
             (X.217) as defined in clause 8 of X.519

COMPLETENESS

  When communicating with a Remote DSA the DUA library is fully confor-
  mant with the Directory Access Protocol detailed in the X.500
  Recommendations/IS-9594 standards.

  Conformance with respect to clause 9 of X.519:

      (i)    All operations defined in the  directoryAccessAC  applica-
             tion  context  (Bind, UnBind, Read, Compare, Search, List,
             AddEntry, ModifyEntry,  ModifyRDN,  Abandon,  DeleteEntry)
             are supported.

      (ii)   Directory Bind security levels of none and  simple  unpro-
             tected are supported.

      (iii)  The directoryAccessAC application context is supported  as
             specified in clause 7 of X.519.

      (iv)   The DUA conforms to the mapping onto used services as  de-
             fined in clause 8 of X.519.

INTEROPERABILITY

  Informal interoperability has been achieved against the ISODE 6.0
  QUIPU Directory implementation.  Interoperability testing against
  other vendors is in progress.

ABSTRACT

  POD (POpup Directory) is an X.500 DUA interface for the X Window Sys-
  tem.  POD is a first attempt at a multiwindow directory tool. It
  offers a simplified interfaces to the basic X.500 operations of read,
  search, list and modify entry.

  POD does not provide any sophisticated access to the DSA.  Operations
  are performed synchronously.  The Directory is thus presented as is,
  i.e.  a hierarchical tree of information, with the user required to
  "navigate" the DIT in order to locate required information.

  POD is available as part of the ISODE release from version 6.0
  onwards.

COMPLETENESS

  88 standard: strong authentication not implemented

INTEROPERABILITY

  Believed to be compliant, though untested.

ABSTRACT

  psiwp is a Macintosh Front End to White Pages service.  It is a
  graphical user interface implementing a partial-DUA.  It is based on
  the ISODE QUIPU X.500 implementation and the Directory Assistance
  Protocol (DAP).

  psiwp is a Macintosh application tailored specifically to provide
  easy access to the Directory for the purposes of performing White
  Pages searches.  Implements User-Friendly Naming scheme developed in
  IETF OSI-DS Working Group.

  psiwp implements a Directory Assistance Protocol (DAP) client.

COMPLETENESS

  Compliant with X.500 standards to the extent that the QUIPU implemen-
  tation is.

INTEROPERABILITY

  Successfully interoperates with QUIPU DSAs

PILOT CONNECTIVITY

  Being used in the White Pages Pilot Project.

BUGS

  Support is available (for registered users of psiwp only) from

RFC 1292                         psiwp                      January 1992


CAVEATS AND GENERAL LIMITATIONS

  psiwp is not a general-purpose DUA. It was designed to be a special-
  purpose front-end for performing White Pages searches and thus, in
  the interests of simplification, does not provide the full range of
  functionality supported by the X.500 standard. A Directory Assistance
  server (available as part of the ISODE distribution) must also be run
  by sites that do not want to run psiwp against either of the two
  White Pages Pilot Project service machines, wp1.psi.net and
  wp2.psi.net.

INTERNETWORKING ENVIRONMENT

  Runs on Macintoshes as a Finder or MultiFinder application.

HARDWARE PLATFORMS

  Runs on Macintoshes that support MacTCP. Requires an ethernet board
  or AppleTalk connectivity. At least 1MB of memory is required, and
  while psiwp will run on most forms of Macintoshes, a Mac-II is recom-
  mended.

SOFTWARE PLATFORMS

  Requires MacTCP 1.0 or later, and Finder (or Multifinder) 6.x (Finder
  7.0 WILL NOT WORK). Requires ISODE Version 6.8 or later.

AVAILABILITY

  psiwp is shareware available for anonymous ftp from uu.psi.com
  [136.161.128.3] in pilot/PSIWP.Hqx.  A nominal fee is charged upon
  registration as a PSIWP user.

ABSTRACT

  QUIPU is part of the ISODE which is an openly available implementa-
  tion of the upper layers of OSI.  QUIPU provides a X.500 Directory
  System Agent (DSA) and a set of Directory User Agents (DUA) aimed at
  different terminal types and modes of interaction

  QUIPU was first publicly demonstrated at ESPRIT in November 1988.
  QUIPU is being used extensively in the European PARADISE project, the
  White Pages Pilot Project and the Australian pilot.  A QUIPU DSA is
  being used at the ROOT node of the Pilot DIT and is being used as
  most country level DSAs.

  QUIPU provides its own solutions to area not specified by the 1988
  standards such as replication and access control.

COMPLETENESS

  QUIPU is aligned to the 1988 ISO IS and the NIST OIW Directory Imple-
  mentors Guide Version 1, with the following exceptions:

      Strong authentication is not implemented.

      QUIPU does not enforce the bounds constraints on attributes,
      filters or APDU size.

      T.61 string formatting characters are not rejected.

      If a DN is supplied with no password in an unprotected simple
      bind, QUIPU does not always check to see if the DN exists.  If
      the DSA connected to can say authoritatively the DN does not
      exist, the association is rejected.  However, if a chain opera-
      tion is required to check the DN, the bind IS allowed.

RFC 1292                         QUIPU                      January 1992



      When comparing attributes of UTCtime syntax, if the seconds field
      is omitted, QUIPU does not perform the match correctly (i.e., the
      seconds field in the attribute values should be ignored, but  are
      not).

      QUIPU always supplies the optional Chaining argument ``origina-
      tor'' even if the CommonArgument ``requestor'' is used.

      QUIPU always supplies the optional Chaining argument ``target''
      even if the base object in the DAP arguments is the same.

      The object class ``without an assigned object identifier'' is not
      recognized unless the ``alias'' object class is also present.

      Non Specific Subordinate References are never followed by a QUIPU
      DSA, but they are passed on correctly to the client if generated.

INTEROPERABILITY

  QUIPU has interworked with a number of other implementations, and has
  no know problems in such interworking.

PILOT CONNECTIVITY

  QUIPU is in use in many directory pilots, certainly including PARAD-
  ISE and the White Pages Pilot Project.

BUGS

  Problems should be reported to [email protected].

CAVEATS AND GENERAL LIMITATIONS

  None.

INTERNETWORKING ENVIRONMENT

  QUIPU users TP0 over X.25, CONS and TCP (using RFC-1006) or TP4 over
  SunLink OSI.

  The DSA knows about the problems of unconnected networks and makes
  chain/refer choices based on the network connectivity.  Using this an
  X.25 only DSA can access data from an Internet only DSA by chaining
  operations through a DSA connected to both networks.

HARDWARE PLATFORMS

  [No information provided--Ed.]

SOFTWARE PLATFORMS

  The ISODE and QUIPU runs on native Berkeley (4.2, 4.3) and AT&T Sys-
  tem V, in addition to various other UNIX-like operating systems.  No
  kernel modifications are required.

AVAILABILITY

  The ISODE is not proprietary, but it is not in the public domain.
  This was necessary to include a "hold harmless" clause in the
  release.  The upshot of all this is that anyone can get a copy of the
  release and do anything they want with it, but no one takes any
  responsibility whatsoever for any (mis)use.

DISTRIBUTION SITES

  The FTP or FTAM distributions of ISODE-7.0 consists of 3 files. The
  source and main ISODE-7.0 distribution is in the file isode-7.tar.Z
  which is approximately 4.7MB in size.

  LaTeX source for the entire document set can be found in the isode-
  7-doc.tar.Z file (3.5MB).  A list of documents can be found in the
  doc/ directory of the source tree.

  A Postscript version of the five volume manual can be found in the
  isode-7-ps.tar.Z file (4.7MB).

  1.  FTP
         If you can FTP to the Internet, then use anonymous FTP to
         uu.psi.com [136.161.128.3] to retrieve the files in BINARY
         mode from the isode/ directory.

  2.  NIFTP
         If you run NIFTP over the public X.25 or over JANET, and are
         registered in the NRS at Salford, you can use NIFTP with usen-
         rame "guest" and your own name as password, to access
         UK.AC.UCL.CS to retrieve the files from the <SRC> directory

  3.  FTAM on the JANET, IXI or PSS
         The sources are available by FTAM from UCL over X.25 using

                 JANET (DTE 00000511160013),
                 IXI   (DTE 20433450420113) or

ABSTRACT

  SD (Screen Directory) is an X.500 DUA interface for character mapped
  screens.  SD is an early attempt to provide quick, easy and user
  friendly access to the Directory.  The following directory operations
  are supported: read, search and list.

  SD does not provide any sophisticated access to the DSA.  Operations
  are performed synchronously.  The Directory is thus presented as is,
  i.e.  a hierarchical tree of information, with the user required to
  "navigate" the DIT in order to locate required information.

  SD is available as part of the ISODE release from version 6.0
  onwards.

COMPLETENESS

  88 standard: strong authentication not implemented

INTEROPERABILITY

  Believed to be compliant, though untested.

PILOT CONNECTIVITY

  DUA Connectivity: SD is in use in many directory pilots, certainly
  including PARADISE and the Internet.

  IBM RISC, Multiple Vendor Platforms, Philips, RFC-1006, Siemens, Sun,
  UNIX, X.25

ABSTRACT

  UCOM.X 500 includes a Directory System Agent (DSA), a directory
  access API, and a set of Directory User Agents (DUAs) for different
  terminal types. UCOM.X 500 is a commercial product based on PIZARRO,
  the research prototype developed at INRIA by Christian Huitema's
  team.

  Some characteristics of the DSA are:

      - The DAP and DSP protocols are provided conformant with the 1988
      CCITT X.500 recommendations.

      - The DIB is maintained in ASN.1 encoded format in the Unix file
      system. Utilities are provided to load and dump the DIB from and
      to ASCII text files.

      - The DIT structure is held in main memory. Additionally, fre-
      quently used attributes may be held in inverted tables in memory
      to speed up searches.

      - Knowledge management: knowledge on managed domains is stored in
      UCOM.X specific attributes of the DSA entries.

      - All X.500 (88) as well as some X.400 (88) object classes,
      attributes and syntaxes are supported. Users may define their own
      classes and attribute types.

      - Schema management: object class and attribute definitions are
      enforced.

      - Simple authentication is provided; strong authentication is not
      currently supported.

RFC 1292                       UCOM.X 500                   January 1992


      - Access control: private mechanisms are provided to allow access
      control lists to be specified for parts of the DIT, to control
      modifications, and to specify access restrictions on attributes.

  The UCOM.X 500 API provides the DAP protocol to applications access-
  ing the Directory. It is a synchronous API which automatically
  manages referrals. Several DUAs using the API, are available. These
  include command line and full screen interfaces for users with ordi-
  nary terminals, and an X-Windows user interface (12/91). An X/Open
  XDS API will be offered shortly.

  UCOM.X 500 is used by French research centers involved in PARADISE, a
  COSINE project. A distributed application to control document
  transfer in a large French hospital, has been built on the UCOM.X 500
  API. It is being used for distributed applications management in the
  French Post Office.

COMPLETENESS

  UCOM.X 500 conforms to 1988 X.500 series of recommendations, as
  specified in paragraph 9 of X.519, with the exception of strong
  authentication.

INTEROPERABILITY

  Interoperability tests with other implementations, e.g. QUIPU, have
  been made in the PARADISE project. UCOM.X 500 is used in the French
  PARADISE pilot.

PILOT CONNECTIVITY

  DSA and DUA connectivity to the PARADISE pilots.  See caveats.

BUGS

  UCOM.X 500 is a commercial product. As such, it is supported and bugs
  are fixed when detected. Bug reports can be sent to our support team
  via electronic mail.

CAVEATS AND GENERAL LIMITATIONS

  The DIT structure is stored in main memory which means that the order
  of magnitude of the number of objects supported per DSA is 10,000. By
  1992 100,000 objects will be supported.

  Not all syntaxes defined in the COSINE and Internet Schema are
  currently supported, and the DUAs do not display photo attributes.
  The Internet DSP is not supported.

  tiple Vendor Platforms

ABSTRACT

  ud is a command line based directory application useful for display-
  ing and modifying white pages information about people.  It runs on
  top of the DIXIE protocol (described in RFC 1246).  ud was developed
  to run under Unix and is currently in beta release within U-M staff
  and a few other places that have heard of it.

  Features include the ability to display and modify the following
  attributes: title, description, commonName, uid, mail, postalAddress,
  homePostalAddress, telephoneNumber, facsimileTelephoneNumber, home-
  Phone.

COMPLETENESS

  ud uses the DIXIE protocol to access X.500 and thus is subject to the
  same completeness restrictions as DIXIE.  It provides Read, Search,
  and Modify capabilities.

INTEROPERABILITY

  Works with the DIXIE server, which works with the QUIPU DSA and DAP
  library.

PILOT CONNECTIVITY

  It has been tested (in conjunction with the DIXIE server) in both the
  Internet and PARADISE pilots.

BUGS

  No outstanding bugs are known.  But reports should be sent to
  [email protected].

ABSTRACT

  VTT X.500 contains a full distributed DSA and a subroutine call to
  dua ( call_dua(parameters)). This subroutine is linked to user's pro-
  cess.  There are two ways for dua to communicate with our DSA called
  dsacvops: a fast communication through shared memory for dua and dsa
  in the same computer and a complete OSI-stack for communicating in
  DAP-protocol with remote dsa's which can be any implementation of
  X.500 dsa, not necessarily dsacvops.  DSA communicates with other
  dsas through a full OSI-stack with protocol DSP or with a shorter
  stack when both dsas are dsacvops-processes.  dsacvops contains a
  special purpose database DIB. VTT X500 contains caching of read and
  search results, access controls (as in Annex F of X.501), object
  classes and attribute types as in X.520 and X.521 and simple authen-
  tication with unprotected passwords in bind. The network level can be
  X.25 or TCP/IP. There are test duas, duacvops, duauser, with a simple
  user interface. Certificates for strong authentication are included
  to x509dua and x509duacvops. VTT X500 is realized with program
  development tools CVOPS and CASN, the code is in C-language and uses
  UNIX System V. The code is fairly easy to port to other operating
  systems.  VTT X500 was made for Smail e-mail product of Nokia Data
  Systems.

COMPLETENESS

  Complete DAP and DSP of 1988 X.500 Recommendations are implemented.
  There are the following omissions: multicasting is not implemented,
  strong authentication of calls to dsa (optional signing of DAP and
  DSP-calls, strong authentication in bind, security error, security
  parameters in common arguments), T61 alternative in CASE IGNORE and
  CASE EXACT STRING, Criteria-syntax, TeletexTerminalIdentifier syntax.

LAST MODIFIED

  Window System, X.25, 3Com

ABSTRACT

  The DUA process runs on 3Com's dual-stack OSI/TCP terminal server,
  scheduled to be released in mid-June 1991.  It provides Presentation
  Address resolution for names, on behalf of the VTP application: when
  the user attempts an outgoing connection ("VTP <name>" or "connect
  <name>"), <name> gets mapped to its Presentation Address.

  The DUA process supports the AddEntry, RemoveEntry, and Search opera-
  tions.  Via a menu-driven command, the system administrator can con-
  figure any of these operations, then send the request to the DSA.  He
  would use the AddEntry operation to enter a resource name and its
  corresponding physical address in the DIB, the DeleteEntry operation
  to remove the name and its physical address, and the Search operation
  (with "filter" as an option) for a display of all registered names
  or, given a name, a display of the name's physical address.

  Regarding unbinding from a DSA, the system administrator could use an
  UnbindDSA command or set a timer which, once expired, would automati-
  cally perform the unbinding.  The binding to a DSA, on the other
  hand, is transparent, provided the system administrator has set a DSA
  address.  The binding is triggered by either an outgoing connection
  attempt or an operation request sent to the DSA.

  The schema supported by the DUA consists of the following sequence of
  object classes: Country, Organization, OrganizationalUnit (up to 3
  levels of OrganizationalUnits are allowed), ApplicationProcess, and
  ApplicationEntity.  Their respective attributes are CountryName,
  OrganizationName, OrganizationUnitName, CommonName, and Presenta-
  tionAddress.  The CommonName of the ApplicationEntity is always "vt"
  for VTP and is transparent to the system administrator.

RFC 1292                   X.500 DUA process                January 1992


COMPLETENESS

  Compliance with the ISO/IEC 9594 standards.
  Handling referrals not yet implemented.
  Schema supported: Country, Organization, OrganizationalUnit,
                    ApplicationProcess, and ApplicationEntity.
  Authentication not supported.

INTEROPERABILITY

  Interoperability with the ISODE QUIPU Directory Service and any DSA
  which strictly meets the ISO/IEC 9495 standards.

BUGS

  [No information provided--Ed.]

CAVEATS AND GENERAL LIMITATIONS

  Deleting an entry will fail if the DUA is interacting with a 6.0
  based version of QUIPU.  This is a bug in QUIPU, and version 7.0
  release will have it fixed.

  Adding a CountryName is disallowed if the DUA is bound to QUIPU.
  This decision was made because to add a country in QUIPU, one needs
  to bind as the manager of the DSA holding the root EDB file, and such
  information may not always be available to the system administrator.
  Also, our binding is done transparently.

INTERNETWORKING ENVIRONMENT

  OSI environments with the complete OSI stack, supporting CLNS and
  TP4.

HARDWARE PLATFORMS

  3Com's OSI/TCP CS/2000 and CS/2100.

ABSTRACT

  Xdi is a Directory User Agent (DUA) for the X Window System.  In
  addition to providing a user-friendly interface,it supports Directory
  interactions of different levels of complexity. Users can select dif-
  ferent window screens to browse, search and modify the Directory.
  There are two different search screens for name based search and
  attribute based search. It is simple to use for novice users but is
  also useful for more advanced users to formulate complex search
  filters.  Xdi also supports "user-friendly naming" in many cases so
  that users are not required to know X.500 naming format.

COMPLETENESS

  The Xdi interface does not support accesses to Delete and Add DAP
  operations as in the 88 Directory Standard. Read, Search, and most
  Modify operations are fully supported. There are no facilities to
  modify the RDNs of entries. Strong authentication is not implemented.

INTEROPERABILITY

  Believed to be compliant. Only tested against ISODE/QUIPU DSAs.

PILOT CONNECTIVITY

INTERNETWORKING ENVIRONMENT

  Same as ISODE.

HARDWARE PLATFORMS

  This software has been tested on SUN4. It is expected that the
  software is portable to SUN3 and other UNIX machines.

SOFTWARE PLATFORMS

  Xdi is expected to run on ISODE (release 6.8 upwards) in UNIX
  environment.  The 'xdi' directory has been designed to fit directly
  into the ISODE source tree. Xdi requires X11R4, the associated Xt
  toolkit and Athena widget libraries.  Also see the operating environ-
  ments of ISODE.

AVAILABILITY

  The Xdi software is available via anonymous FTP from
  thumper.bellcore.com in file pub/xdi.tar.Z. Source code and execut-
  ables can be freely distributed or modified for non-commercial and
  non-profit use provided that all copyright notices, permission and
  nonwarranty notice included in the software distribution remain

ABSTRACT

  Xds is a DUA designed for users who have little or no knowledge of
  X.500. Its intended to be used, for example, by a receptionist who
  has to answer such queries as 'Could I have the telephone number of
  Andrew who works in Research?'. The display is customized for the
  particular organization and the results of the search are presented
  in the format of a business card. It is possible to customize the
  displayed information.

COMPLETENESS

  Xds does not provide user access to all the services provided by
  X.500.  Instead, Xds uses X.500 services to provide the specific
  functions for which it is designed to provide.

  Conforms to section 9 of X.519.

ABSTRACT

  The xdua is a DUA designed to be used by DSA managers who have suffi-
  cient X.500 knowledge to manipulate the Directory Information Tree
  (DIT). It's typical use is to maintain the information stored on a
  DSA. The xdua has a Macintosh style interface.  This simplifies
  browsing the DIT hierarchy.  A user can traverse the DIT levels by
  using a standard mouse.  The xdua supports the X.500 operations of
  add, modify, delete, search and show.

COMPLETENESS

  Uses the QUIPU (ISODE) dsap interface to provide the X.500 opera-
  tions.

  Conforms to section 9 of X.519.

INTEROPERABILITY

  Only tested against the QUIPU (ISODE) DSA.

PILOT CONNECTIVITY

ABSTRACT

  The xwp program is a simple browser for the QUIPU/X.500 directory.
  It uses OSF/Motif and the X Window System to provide a convenient
  user interface.

  The user interface consists of five different top-level windows: the
  main window, the search window, and three option windows.  The main
  window appears when the program is executed and all others are
  reached through its menus.  The main window contains Current Loca-
  tion, Current Descendents, Descendent Filter, Current Information,
  and Directory Status subwindows.  The contents of these subwindows
  show information about the current location of the browser in the
  directory tree.  The search window contains Search Area, Search
  Filter, and Search Results subwindows.

  The mouse pointer may be used in the main window to change the
  current location of the browser in the directory tree.  We can des-
  cend deeper into the tree by clicking the mouse when it points to a
  member of the Current Descendents list.  Doing this "moves" the
  browser to this new (one level deeper) location in the directory
  tree.  This causes the main window to be updated as follows: (1) the
  selected descendent becomes the new Current Location, (2) its descen-
  dents are listed in Current Descendents, and (3) its contents are
  displayed in Current Information.  Any problems and messages from the
  directory are displayed in the Directory Status portion of the main
  window.  To move the browser up the directory tree (i.e. towards the
  root), click the mouse pointer on one of the components of the
  Current Location.  In this way it is possible to move the browser to
  any location above its current position (i.e. to any ancestor) in one
  mouse click.  Doing this causes the main window to be updated as dis-
  cussed above.  Due to directory-imposed limits, it may not always be
  possible to display all the descendents of the current position.  In
  such cases (and others) it may be useful to impose a filter on the

  descendents to be listed.  To do this, position the mouse pointer in
  the Descendent Filter box and use the keyboard to type in the desired
  filter expression.  Typing <RETURN> in this box causes the Current
  Descendents list to be updated using the new filter.

  xwp was developed at the University of Wisconsin - Madison Computer
  Sciences Department. It is used in conjunction with the ECI mail user
  agent project.  xwp was written by Robert Lazarus, III.
