[Samba] Samba as a Member-Server with a WIndowsServer2022-PDC

[Matthias Reichenbach von Nordheim]

Hi there,

I try to join a Samba-Server (4.17.12) in a WindowsServer2022 Domain 
(net ads join -U...).

The result is:

Failed to join domain: failed to lookup DC info for domain 'HMW.DE' over 
rpc: Indicates a referenced user name and authentication information are 
valid, but some user account restriction has prevented successful 
authentication (such as time-of-day restrictions).

DNS is working fine:

sh-4.4# nslookup
 > set type=SRV
 > _ldap._tcp.HMW.DE
Server:         192.168.10.1
Address:        192.168.10.1#53

_ldap._tcp.HMW.DE       service = 0 100 389 srv-pdc.hmw.de.

I tried different credentials from administrator group and administrator 
himself - no success.

I've googled my fingers to the bone, but I can't find the correct 
setting in group policy editor on my pdc (and yes, I gpupdated the 
settings everytime with /force).

Has anybody a idea for me?

Thanks a lot.
