[TriLUG] pam help

[Ryan Leathers]

I have a Redhat 9 system which is not allowing interactive console or remote
login.  
It used to.

I bounced it into single user and checked nsswitch, passwd, shadow...
nothing fishy there.

I'm hearing a third hand story that someone may have been applying RPMs and
futzing with this host in order to allow ldap authentication, but a find
-newer didn't turn anything up that seemed important to me, and the person
who allegedly did the deed went on vacation.

My guess is that I need to look at pam.  This is probably because I don't
know much about pam and the unknown makes for a handy scapegoat.  So, my
question for the pam-aware before I go off half cocked... are my symptoms
described above things which may result from pam trouble?
