Hello,

I realize I didn't provide the relevant information... Sorry,

our current domain includes two Windows Server 2019 domain controllers with a functional level of "2016". The Samba server is also at 2016... Samba 4 is version 4.23.
The join command is: samba-tool...

Good evening,
I must first congratulate you on the clarity of your documentation; it allowed me last June to set up my first Samba AD controller with my two other Windows 2019 DCs.

Unfortunately, since then, a major server failure has damaged our Active Directory, and I can no longer...
