Description Peter Trifonov 2015-07-27 10:56:30 UTC
Replication from a Samba domain controller to Windows Server 2008 R2 domain controllers to fails. Windows tells "The replication operation failed because of a schema mismatch between the servers invoked."   
Replication from Windows to Samba seems to work.

Samba tells the following:
# samba-tool drs showrepl

Please retry with Samba 4.5rc1. 

We have fixed a lot of schema bugs in this release.
