.Sh DESCRIPTION
|
|
The
|
|
.Nm YP
|
|
subsystem allows network management of passwd and group file
|
|
entries through the functions
|
|
.Xr getpwent 3
|
|
and
|
|
.Xr getgrent 3 .
|
|
.Nm YP
|
|
also provides hooks for other client programs, such as
|
|
.Xr amd 8
|
|
and
|
|
.Xr bootparamd 8 ,
|
|
that can use
|
|
.Nm YP
|
|
maps.
|
|
.Pp
|
|
The
|
|
.Nm YP
|
|
subsystem is started automatically in
|
|
.Pa /etc/rc
|
|
if the directory
|
|
.Pa /var/yp
|
|
exists.
|
|
.Sh BUGS
|
|
Only
|
|
.Nm YP
|
|
client functionality exists, there is no ypserv (yet).
|
|
.Pp
|
|
.Pa /etc/passwd
|
|
and
|
|
.Pa /etc/group
|
|
only support ``+'' entries, not the more sophisticated entries like
|
|
``+user'' and ``+@netgroup''.
|
|
.Pp
|
|
If
|
|
.Xr ypbind
|
|
cannot find a server, the system behaves the same way as Sun's code:
|
|
it hangs.

.Sh HISTORY
|
|
This free
|
|
.Nm YP
|
|
subsystem was written from scratch by Theo de Raadt to be compatible
|
|
to Sun's implementation.
