I also use LDAP (Openldap). Scott Balneaves wrote up a tutorial on how
to get authentication working a while back.  It can be found here:

Follow the section for Client: install client pieces.  For my systems,
I added just the ldap-auth-client.    I answered the questions. I
changed the ldapi:/// to ldap://IP.x.y.z:389/ ... I also entered the
correct info for the realm.  I answered yes to the question about
having root be able to change passwords, and no for the authentication
required to access the database.

Next, I copied/pasted the example profile changing given on the above
page, only I changed edubuntu to something appropriate for our school
and saved it as ncs-ldap-config.

I then invoked auth-client-config -a -p ncs

Afterwards I was able to use ldap.  I now have 7 servers all
authenticating successfully following this approach. Many thanks to
Scott for help with that wiki page.
