[CentOS] Howto for LDAP authentication with replication

In fact Kerberos and LDAP are two great tastes that go well together.

Keep user information and authorization information in LDAP while keep user authentication information in Kerberos.

Later you could try to keep Kerberos authentication information in LDAP with Heimdel (spelling?) Kerberos (like MS AD does) though many purists feel this compromises the whole Kerberos security principal. Maybe it does, but it sure makes for easy redundancy.

Thank you for the info.  I understand that LDAP and authentication are
not the same thing.  We use LDAP within our organization for storing
other types of data but most of the staff do not like to deal with it.
 In fact some team members were opposed to using LDAP for
authentication, now I understand why!  It seems to be a pain in the
ass to learn how to use and configure.

At this point I am leaning toward using kerberos instead.  It took me
20 minutes to get a working kerberos server installation up and
running, and I can now easily add new users and authenticate them,
manage tickets, etc.  Now I understand what you meant about LDAP not
being designed for authentication.  Thank you again for your time,
Craig.  This was a good learning experience for me.

thanks

Sean
