On all machines, confirm that the domain name is set properly
(just enter "domainname" and verify it).  On the master, make sure
ypserv is running.

Now, if the clients really are clients (and not slave servers), you
simply need to do a couple of things:

1. Edit /etc/yp.conf on the CLIENTS and make sure there is a line such
as:

	ypserver name-or-IP-address-of-master

in it.

2. Edit the /etc/nsswitch.conf file on the CLIENTS and modify the lines
for "passwd", "shadow" and "group" to include "nisplus nis":

	passwd:	files nisplus nis
	shadow:	files nisplus nis
	group:	files nisplus nis

3. Restart ypbind on the clients:

	service ypbind restart

4. Test the clients to make sure they're picking up the map you want:

	ypwhich -m

That should do it.
