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!
