Samba-3 is not, and cannot act as, an Active Directory server. It cannot truly function as an Active Directory
PDC. The protocols for some of the functionality of Active Directory domain controllers has been partially
implemented on an experimental only basis. Please do not expect Samba-3 to support these protocols. Do not
depend on any such functionality either now or in the future. The Samba Team may remove these experimental
features or may change their behavior. This is mentioned for the benefit of those who have discovered secret
capabilities in Samba-3 and who have asked when this functionality will be completed. The answer is maybe
someday or maybe never!
To be sure, Samba-3 is designed to provide most of the functionality that Microsoft Windows NT4-style
domain controllers have. Samba-3 does not have all the capabilities of Windows NT4, but it does have
a number of features that Windows NT4 domain controllers do not have. In short, Samba-3 is not NT4 and it
is not Windows Server 200x: it is not an Active Directory server. We hope this is plain and simple
enough for all to understand.
