samba - Jun 2017 - Cant Replicate Schema Updated With Adprep

I have a very old domain i inherited that is running samba 4.5.6 but is on
schema version 30.

I added a windows 2003 DC and used the 2008r2 adprep.exe utility to upgrade the
schema to version 47.  To do so the 2003 server had to take the schema and
infrastructure roles.

I am now trying to use the repadmin utility to sync the schema back to samba to
it is failing with the following:

[2017/06/09 16:34:11.855939,  0]
../source4/dsdb/repl/replicated_objects.c:245(dsdb_repl_resolve_working_schema)
  Can't continue Schema load: didn't manage to convert any objects: all
131 remaining of 133 objects failed to convert
[2017/06/09 16:34:11.856945,  0]
../source4/dsdb/repl/replicated_objects.c:358(dsdb_repl_make_working_schema)
  ../source4/dsdb/repl/replicated_objects.c:358:
dsdb_repl_resolve_working_schema() failed: WERR_INTERNAL_ERRORFailed to create
working schema: WERR_INTERNAL_ERROR

Is what I’m trying to achieve possible?

Thanks
Danny

Hi,

Is it possible to join a new Samba DC to this domain? The join code
should be more robust. This kind of upgrade is intended to work, but we
need more automated testing in this area. Otherwise, we will be trying
to improve this process when we attempt to upgrade to the newer 2012 and
above schema, hopefully in the coming months.


Cheers,

Garming
