an authentication problem

[Paula J. Lindsay]

Hi everyone,
I just set up a RHE 4.  I got it registered with RH and the updates 
going so I thought everything was fine.  Then the lab called
me back, they weren't able to log in.  I looked at the messages and I 
see the people who tried to log in, which is everyone in
this particular lab, and they are all getting the same error:

Jan  4 10:32:45 leila sshd(pam_unix)[12276]: 2 more authentication 
failures; logname= uid=0 euid=0 tty=ssh ruser= rhost=serendipity  
user=felitsky

when myself or someone that is not in the lab logs in it is fine.  Can 
anyone help me out.  I've checked off the firewall, exported
the users from their home directory, but it didn't fix the problem.  Can 
any help me?  Has this happened to anyone out there
in RH world?  Many thanks in advance for any help.
Paula
