pam_ldap and nss_ldap configuration

Hi Friends,
I am using open ldap server and padl's pam_ldap and nss_ldap as clients for login/user authentication for my system. I have installed all these. Please let me know how can i configure properly to authenticate the users.
I searched for samples on the internet, but couldn't find a proper one.

Please let me know how can i configure??

Thanks and Regards,
Vijay S.
