Dave,

thanks for the helpful tips.  I was able to resolve the problem though.

Overall, it was a pam problem.  By default, pam was only using DES
hashing to check passwords, which was causing any user with a password >8
characters to fail authentication.  Updating the pam rpm correctly
implemented the MD5 hashing, which resolved the problem.

As seen on bash.org:
The problem with America is stupidity. I'm not saying there
should be a capital punishment for stupidity, but why don't
we just take the safety labels off of everything and let
the problem solve itself?
