Michael, thanks for the reply.
The state: the replication seems to work, but winbind doesn't work
correctly (afaik) on that adc1.
So shares like SYSVOL aren't accessible.
It seems I can only retry demoting, cleaning up and join again, plus
transfer that idmap.tdb.
Packages are up to date, I *should* have all necessary packages installed.
