Thanks to all for their help.  I was able to resolve the problem by copying
/etc/nsswitch.nis to /etc/nsswitch.conf.  Apparently somethings was amiss
with my manually edited nsswitch.conf file.  Thanks go to the following
people for their input:

David Foster
Darren Dunham
John Timon
Charles Homan
Casper Dik

Their replies were:

--------
It would help to see your nsswitch.conf. If your passwd and
group entries are correct, then you don't need the +... entries
in /etc/{passwd,group}.

So it sounds like the passwords aren't correct.
You showed the passwd and group entries, how about shadow?

ypinit -c to setup the client

make sure that your nis servers (master and slaves) are in /etc/hosts

make sure domainname is set also.

Hey, Jeff, this isn't an answer to your question (unfortunately.)  I just
wanted to point out that you don't actually need the "+:" entries in passwd
or group.  Just make sure the lines in /etc/nsswitch.conf look like:

passwd:    files nis
group:     files nis

As to your problem, could something be wrong with your shadow file?  For
instance, I don't recall if in the "+:" case you need a similar line in
shadow or not.  I believe that if you are root when you su it doesn't bother
checking the shadow file, so that would be why it works for root but no one
else...

Good luck!

Did you run pwconv?

Did you add a "+::" entry to /etc/shadow?

(Withpout the "x").

The proper way to create a compatibility client is this:

	Change passwd line in nsswitch.conf to "passwd: compat"
	Add "+::::::" line to /etc/passwd
	run "pwconv" (will update passwd to include "x" and create
	shadow entry)

Managers,

I will be the first to admit that I am not a guru when it comes to
YP/NIS, and I would like to ask a hopefully simple question.

I am attempting to add a new NIS client to my domain.  I have modified
nsswitch.conf to use the proper compat entries for passwd and group.  I
added the proper entries to /etc/passwd (+:x:::::) and /etc/group (+:).
Automounting is also working correctly.

Here is the strange part:

When I am logged in as root, I am able to su - username with no
problems.  The user logs in, has their home directory, and all is well.
However, when I am logged in as a user and su to another user (not root)
the users password is never accepted.  I also cannot login as a non-root
user directly using SSH.  SSH keys are accepted without problem for that
user, but passwords are not.

I know that I am overlooking something simple.  Can anyone clue me in?
Also, I have been looking for good online NIS references and have not
had the best luck finding one.  Any suggestions?

Thanks, and I will summarize,
