"schema enhancements [...] are currently not supported by Samba." Does this applies only when connecting a Samba DC on MS AD or is the replication broken also when we enhance schema on Samba-only-domain? Cheers, mathias @Marc, as you can imagine I'm not too aware about schema modification and Samba replication restriction, but it seems this Office Communication Server schema enhancement is the reason of your issue. 2015-07-14 21:45 GMT+02:00 Peter Trifonov <petert at dcn.icc.spbstu.ru>:> Hello Marc, > > > > What schema version does your AD have? > > http://www.itguydiaries.net/2012/09/how-to-find-current-active- > > directory.html > > > > Samba is shipped with AD schema 47 (MS Windows Server 2008 R2).

Windows 2012 DCs or other Windows DC with exchange installed) and replication didn't fail anymore in such environments. " Do I need to enable something in Samba configuration files to let this working? Is it safe to run Samba in a domain with modified schema? Can I ignore windows complaining on replication issues with Samba? Actually I need samba domain controller in order to deploy SOGo, which requires its own schema modifications. Can I proceed with its installation before resolving the problem with replication? With best regards, P. Trifonov
