[Samba] help with chrony time synchronisation

It's the thread I mentioned earlier, after re-reading the thread, I 
gather that NT5DS  just doesn't work with chrony with samba 4.21 onwards 
(now I'm running 4.22.3) and clients need to switch to NTP, or is there 
a different solution that makes nt5ds, default windows domain joined 
pc's setting, that I somehow miss in this thread?

Although there were mentions in the same thread, that it works for some 
people.

I noticed, that when comparing to information about samba/chrony here

http://samba.bigbird.es/doku.php?id=samba:install-chrony

that requests, that my client send (in nt5ds mode) don't have "key id" 
and "authentication" in packets captured by tcpdump.


Also definately my setup was working before.

I would be very glad If someone confirmed that has working time service 
with similar config (samba 4 on debian bookworm with chrony 4.22.3+ and 
windows clients using nt5ds, default for domain joined clients).

Regards,

Kacper Wirski
