I would be most helpful if you could:
- file a new bug with a clear description of only the objectClass
- determine how the objectclass ordering algorithm works on Windows to
allow this auxillary class to be added. The WSPP documentation may be
of assistance here. MS-ADTS in particular:
- provide a patch to source4/dsdb/tests/python/ldap.py to demonstrate
the correct objectClass ordering behaviour
- provide a patch to source4/dsdb/samdb/ldb_modules/sobjectclass_sort.c
to implement the correct sorting.
Only this process will get this issue fixed.
I've CC'ed Matthias, who has worked on many of our LDAP behaviour issues
in the past, and who may be able to provide some further assistance, as
I'm currently too far stuck in IDMAP for s3fs to try and take this on in
the near future.
