samba - Dec 2024 - Modify replication topology?

It happens that my current replication topology goes via less connected hosts,
and I would like to change that to have more available/connected hosts at the
center of the star, or add manual replication routes in addition. Is there a way
to modify the created DC replication topology?

I also tried to manually replicate following
https://www.blackhole-networks.com/Cheatsheets/Samba4Rep/ but I got errors like

ERROR(<class 'samba.drs_utils.drsException'>): DRS connection to
DC1 failed - drsException: DRS connection to DC1 failed: (3221225524, 'The
object name is not found.')

Any advice?

Thanks, Joachim
