Cannot Login using GUI

[James Cooley]

Run the authconfig command from single user mode and disable ldap 
authentication that way.  There are many files that are changed by the 
authconfig utility, including /etc/pam.d/system-auth, 
/etc/nsswitch.conf, and /etc/nscd.conf, which are probably causing your 
problems.   The authconfig will make the necessary changes to all of 
these files saving you quite a bit of work.

If you need help on setting up ldap authentication, I might be able to 
help you out through private emails, since I've had a great deal of 
experience dealing with it.
