On Samba4 DCs we run the smbd from git-master/source3 as a separate process 
with passdb backend samba4, offering sysvol as well as traditional file and 
print services.

On Memberservers we run the 3.5.11 smbd (avoiding some bugs in 3.6.x).

For single server setups file and print can be served by the smbd running on 
the Samba4 DC but for higher stability demands we recommend providing 
additional file and print services on a memberserver.

IDmap maintenance on the Samba4 DCs is done automatically based on the posix 
IDs that are stored in an OpenLDAP directory. This automation gets triggered 
by  our S4 Connector process that synchronizes Samba4 objects with OpenLDAP 
objects. An NSS ldb module for the idmap would have been an option too.
