DESCRIPTION
     The NIS subsystem allows network management of passwd and group file
     entries through the functions getpwent(3) and getgrent(3).  NIS also pro-
     vides hooks for other client programs, such as amd(8) and
     rpc.bootparamd(8), that can use NIS maps.

     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 ``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 /var/yp/Makefile.yp.

     The NIS subsystem is conditionally started in /etc/rc.  See the
     /etc/rc.conf file for configuration variables.

HISTORY
     The NIS client subsystem was originally written by Theo de Raadt to be
     compatible with Sun's implementation.  The NIS server suite was origi-
     nally written by Mats O Jansson.

BUGS
     If ypbind(8) cannot find a server, the system behaves the same way as
     Sun's code: it hangs.

     The `secure map' feature is not compatible with non-BSD implementations
     as found e.g. in Solaris.
