[Samba] Samba newbie question...

[daveman at bellatlantic.net]

Can Samba be used as a complete replacement for a Windows 2000 Active Directory server? I have some vague notion that this can be accomplished by using a combination of OpenLDAP, Samba, MIT Kerberos, and the OpenAFS file system. To say the least, the descriptions I have found have been vague as to whether or not I will be able to completely replace the functionality of an Active Directory server with a similar setup.

If this is possible, could someone point me to reasonably good documentation on the subject?

Thanks so much.
