Description Arvid Requate univentionstaff 2018-09-04 16:52:13 CEST
Also backport for UCS 4.2

+++ This bug was initially created as a clone of Bug #47441 +++

We have two reports of admins experiencing a block in DRS replication, showing symptoms of https://bugzilla.samba.org/show_bug.cgi?id=12972 . I checked the Samba 4.7.5 version we ship with UCS 4.3 and the proposed upstream patch applies. I think we should ship it as erratum to avoid other people running into this for newly joined UCS Samba/AD DCs.

Upstream patch (from Bug #47441) needed adjustment in one patch hunk, otherwise it applied cleanly.
