[Samba] Upgrade from 4.9.8 to 4.10.3 on Centos using Sernet Packages

Fri May 24 06:24:40 UTC 2019

Hello you all,
I did some more tests used Samba 4.10.4 and still the same Problem. I
also upgraded all the DCs and the problem is the same on all of them.
Downgraded all of the an problem is gone.

I went up to loglevel 5 an saw nothing that was related. How do I debug
further?

@rowland: I wrote to bugzilla-maintenance at samba.org to get an bugzilla
account but haven't gotten any feedback. What else can I do?

Regards

Christian
