Correct, you don't mix CTDB replication with the AD replication used in
the AD DC. 

If you are using CTDB, then your data is important enough to afford
distinct servers for your AD DC.  The two replication schemes cannot be
combined, they are at different layers.

You can of course use CTDB with a Samba 4.0 file server, in the same way
you can replicate a Samba 3.6 file server.  

The CTDB folks can fill you in on the status of CTDB with Samba 4.0, but
I understand it is fully supported.
