[Samba] Time sync problem samba 4.20.0 chrony debian11

[Daniel Müller]

After a alot of try and error . I just could not get it work . 30 percent of our 200 clients
had the right time other 70 percent refused!

So I did it an very old way: set gpo domain users can change  local time.
Set in a logon.bat : net time \\my.domain.server  /SET /YES
And erverything is working. Time is ok. My databases don not refuse anymore.

Greetings
Daniel

Hi folks,

I have tested with both Windows 10 22H2 and Windows 11 23H2, both domain joined. Time synchronization with a Samba AD DC 4.20.1 (Debian Bookworm
backports) does not work. Either has M$ changed something, or Chrony. 
Unfortunately, I haven't got time to dig deeper in this at the moment. 
It worked about 18 months ago...

Best regards,

Peter
