Screwed up the DC2 now as well. Nice day.

Somehow I overlooked some "stretch" string below "sources.list.d", this
lead to rm-ing samba (and smb.conf etc) ...

Now I have that back up, but it seems I lost some tdb-files or so.

samba-ad-dc.service fails ...

and it seems the cronjob with the samba4-backup didn't run on that machine.

I assume I have to start over: demote that DC2 etc

Should have left office when I could an hour ago.
