Yes, one of the key advantages to a Samba4 domain over our previous
domain technologies is that we have full support for bidirectional
replication of the AD database with Windows. As is mentioned, sysvol
replication is not fully implemented yet (but FRS is being worked on for
this purpose). Also, you will want to use bind9_dlz or Kai's upcoming
DNS server (when it supports updates, which should be soon) so that the
DNS information is in the replicated directory.
I understand Samba4 has even been used as a migration tool, allowing it
migration of a domain that has started at Samba3 and needed to run
The big thing we don't have is multi-domain in a forest support. We
have many of the parts, and know how we could promote a Samba3 domain
into an existing AD forest, but we can't do it quite yet.
