Sh DESCRIPTION
The
Tn NIS
subsystem allows network management of passwd and group file
entries through the functions
Xr getpwent 3
and
Xr getgrent 3 .
Tn NIS
also provides hooks for other client programs, such as
Xr amd 8
and
Xr rpc.bootparamd 8 ,
that can use
Tn NIS
maps.
Pp
Password maps in standard YP are insecure, because the pw_passwd
field is accessible by any user. A common solution to this is to
generate a secure map (using
Dq makedbm -s )
which can only be accessed by a client bound to a privileged port.
To activate the secure map, see the appropriate comment in
Pa /var/yp/Makefile.yp .
Pp
The
Tn NIS
subsystem is conditionally started in
Pa /etc/rc .
See the
Pa /etc/rc.conf
file for configuration variables.

Sh HISTORY
The
Tn NIS
client subsystem was originally written by Theo de Raadt
to be compatible with Sun's implementation. The
Tn NIS
server suite was originally written by Mats O Jansson.
Sh BUGS
If
Xr ypbind 8
cannot find a server, the system behaves the same way as Sun's code:
it hangs.
Pp
The
Sq secure map
feature is not compatible with non-BSD implementations as found
e.g. in Solaris.
