I have a strange problem on a CentOS-5.8 machine. I can only login as root. If I try to login with one of the user's names, it hangs for a long time. I thought it hung forever, but I just found that I do login after "su tim" after 5 minutes.
It seems that the problem lies in repeated messages in /var/log/messages

The openldap server is not running, and I don't see why this authentication is being sought. There is nothing in /etc/pam.d/su or /etc/pam.d/login or /etc/ssh/sshd_config to suggest that ldap needs to be invoked, unless it is a part of system-auth .
---- it would seem that you configured ldap as a potential authentication source in 'authconfig'
Tait probably gave you the best possible fix - remove the ldap entries in /etc/nsswitch.conf (or /etc/sssd/sssd.conf if present).
