seems that 92_bug27027_keep_existing_option_for_domain_join_dc.patch.DISABLED is missing?

Did you use the latest unreleased errata updates?

Comment 2 Arvid Requate

Disabled since UCS 4.1-4

4.1-0-0-ucs/2:4.5.1-1-ucs4.1-4/92_bug27027_keep_existing_option_for_domain_join_dc.patch.DISABLED

I'll check if we can remove in from univention-samba4 now or if we need to merge the patch.

Comment 3 Arvid Requate

I've updated and re-activated the patch, now re-join works again.

Advisory: samba.yaml

The version number is not yet up to date due to Bug #43144.

OK - rejoin, sid not changes, 
     join.log:
     Joined domain FOUR (SID S-1-5-21-854837004-1585209202-1099490383) as a DC
