did you check /var/log/secure on that system? That should log
remember, each machine must make it's own connection to ldap and each
system has it's
own /etc/ldap.conf, /etc/openldap/ldap.conf, /etc/nsswitch.com
and /etc/pam.d/system-auth files

winbindd would only slow things up - especially if improperly
also, it's a good idea to make sure nscd is stopped - at the very least,
stopped until everything is working properly.

very important on systems with system users in /etc/passwd and network
users in ldap since it gives you the hybrid.
very important also to not have a user in both /etc/passwd and ldap as
that would surely cause confusion
