I apologize in advance for going slightly off topic, but I have never setup a centralized authentication scheme under Linux. My question is, what do most people do for centralized command line, X, and PG authentication? From what I’ve read the main choices are NIS or LDAP. LDAP would be problematic as I would have to embed a login and plain text password in the ldap.conf file for binding to the MS AD.
It sounds like PAM would be useful for you. That's really what is was built for. --Scott
