[Samba] [PATCH] Re: Failing replication

Mon Feb 24 01:04:38 UTC 2020

G'Day Alexander,

This is looking trickier than I had hoped.  I don't think the patch I
included is the right approach, and I can't reproduce what I thought
was the issue on master.

I've added a test in MR 
https://gitlab.com/samba-team/samba/-/merge_requests/1128 but that just
shows that what we were doing still works, so it isn't terribly useful
in your case.

I'm sorry that I don't have a really good next step, something DB-
specific appears to be going on, particularly as you then get another
error once we fix this one.

Sorry!

Andrew Bartlett
