Red Hat Enterprise 6 client issues

["Sotomayor, Vicente (ITD)" <vicente.sotomayor@state.ma.us>]

Hello,

I'm testing RH 6 Openldap clients and I getting a lot of errors and poor performance while trying to login and also takes serveral minutes for a su - command to work. We are using SSL.
I'm seeing plenty of "errors ldap_result() timed out" in the messages file and it also states that it can not contact either ldap server. I enabled root to temporarily ssh and that even takes up 2 minutes. Our RH 5 clients are having no issues. Does anyone know the fix?

Thanks
