samba - Sep 2023 - oining_a_Samba_DC_to_an_Existing_Active_Directory

Hello I try to join a new dc to a domain like there:

https://wiki.samba.org/index.php/Joining_a_Samba_DC_to_an_Existing_Active_Directory

Join is OK.

INFO 2023-09-14 14:46:12,558 pid:718 
/usr/lib/python3/dist-packages/samba/join.py #1599: Joined domain SAMDOM 
(SID S-1-5-21-.....) as a DC

But replication failed:
