.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.
