In /var/log/messages, I see (among thousands of other entries) the following:
Aug 2 18:58:37 localhost gdm: pam_ldap: ldap_simple_bind Can't contact LDAP server
Aug 2 18:58:38 localhost gdm: Couldn't set acct. mgmt for userid-omitted
This would be after a power failure while I was logged in. It was locked up, so I cycled power. I didn't try to log in until this morning.
I'm not aware of having LDAP installed. How would I reset this?
Q: if there's an authentication problem, through LDAP, why wouldn't it affect ROOT?
