I've installed NIS and it is working, but I'm having a problem with the shadow
file. (I'm using MEPIS systems for the server and the client I'm testing.)

The default config on my system is using /etc/shadow, so I specified to
include shadow in /var/yp/Makfile, but my client system is still not getting
passwords (I can't ypcat shadow and when I try to login as a user from the
server, I get an "Authentication service cannot retrieve authentication
info." error message). I did "ps -ax" and found this line:

/usr/sbin/rpc.yppasswdd -D /etc -e chsh

But in a howto (http://www.tldp.org/HOWTO/NIS-HOWTO/ypserv.html), it says to
start rpc.yppasswdd with:

rpc.yppasswdd -s /etc/yp/shadow -p /etc/yp/passwd -e chsh

So here's my main concern: If I change the line in /etc/init.d/nis from the
first line listed to the 2nd line, will it get clobbered at some point during
a system update from apt-get?

Is this the best way to fix this, or is there some better way to either merge
the passwd and shadow file (I've heard it might not be a good idea to use
shadow passwords for NIS)? And why is it that when I have this line in the
Makefile:

ALL = passwd shadow group hosts rpc services netid protocols netgrp

(also, later is the line "ALL += shadow")

the shadow file is not passed on? (I also tried it first without "shadow" in
the first line.)

Thanks for any help on this.

Hal
