Has anybody out there used the Zimbra OpenLDAP service to do System authentication (like using PAM-LDAP, etc)? I have setup and configured FreeRADIUS to use the Zimbra LDAP successfully but have had very little luck in getting the system LDAP services (like NSS-PAM, or the other LDAP system utilities) to work because I keep getting schema errors. Anybody have experience with this? Not really looking for a huge manual on how to do this just wanting to know if somebody has done it and a quick summary of the best way to accomplish it. (without ruining Zimbra preferrably)
