Sh DESCRIPTION
The
Nm
utility offers an easy way to test PAM modules and policies from the
command line.
Pp
The
Nm
utility loads the PAM policy specified by the
Ar service
argument, starts a PAM transaction by calling
Xr pam_start 3 ,
then executes the primitives specified by the remaining command-line
arguments.
Finally, it ends the transaction by calling
Xr pam_end 3 .
Pp
The commands are:
Bl -tag -width 6n
It Cm authenticate , Cm auth
Call
Xr pam_authenticate 3 .
It Cm acct_mgmt , Cm account
Call
Xr pam_acct_mgmt 3 .
It Cm chauthtok , Cm change
Call
Xr pam_chauthtok 3
with the
Dv PAM_CHANGE_EXPIRED_AUTHTOK
flag set.
It Cm forcechauthtok , Cm forcechange
Call
Xr pam_chauthtok 3
with no flags set.
It Cm setcred , Cm establish_cred

Sh BUGS
The
Nm
utility does not (yet) support setting and getting individual PAM
items or environment variables.
Pp
The
Nm
utility does not afford the user complete control over the flags
passed to the
Xr pam_authenticate 3 ,
Xr pam_acct_mgmt 3 ,
Xr pam_chauthok 3 ,
Xr pam_setcred 3 ,
Xr pam_open_session 3
and
Xr pam_close_session 3
primitives.
