I am interested in moving to Samba4 for the domain control side of things, but the twist is that I have many other things relying on OpenLDAP for authentication and configuration, with several custom schemas.

I currently ask myself the same question as Alex, so thanks for
(re-)pointing us at the wiki. After reading both the normal samba4/howto
and the upgrade-howto, here are my questions:
- If I understand it correctly, s4 will replace the currently running
- Did anyone ever think about setups where the slapd is not running on
the same machine as the samba3? (And where joining both on a single
machine is not wanted?)
- Did anyone ever think about setups where two or more machines run
slapd with multi-master replication?
Even if we could go on without multi-master and be content with having
one (virtual) machine serving both as master for all the ldap-based
authentication (with read-only mirrors) and as the master for the
- The migration-howto doesn't mention at all what happens with the
additional schemes installed on the ldap and seems to only assume that
standard samba3-schema and posix/inetorgperson is active?
- Is it possible to read-only replicate at least the unix (and custom)
schemes to second servers? How would that be configured?
Thanks for answering and have a good day,
