when I provisioned the first DC I didn't know the idmap ldb: use rfc2307
option so up to now idmap ldb:use rfc2307 = yes is not present in
primary DC neither in the secondary.

Can I enable it now without brake something?
How should I proceed to enable it?
Should I just add the statement in smb.conf and restart samba or do I
have to do something else?
Is there a order to follow having 2 DCs?
Does it matter if I have beta3 on primary DC and rc1 on secondary?

Thanks,
Daniele.
