I'm trying to join samba to a Windows 2003 domain in which I did the adprep to be able to add windows 2012 servers. During the replication it fails because the top objectclass has new attribute and can't be transformed into a ldb object at the first iteration. As the constructed schema lacks a top objectclass the creation of the accessors fails causing a fatal error in the replication.
I don't think the problems still exists we did the fix with metze on this I propose to close the bug.
Closing out bug report. Please feel free to re-open if it's still an issue.
