Havinig problems with NIS

[Daniel Glenn <danielrg@ms3.hinet.net>]

Here at White Horse we had some local college students setup our LINUX
network. They've gone home for the summer, so we're doing things on our
own. I've spent some time trying to find out how to addusers that can be
accessed across the whole network, but have been unable to do so. 

We are running RedHat 6.0. I know everything is working, I can log into
my account from anywhere on the network. But I cannot figure out how to
add a new user. Where is the file that I modify for this? What do I put
in? I found the passwd file that linuxconf adds to, but I can't find the
file that NIS wants.
