We should add a hint to the UCS@school admin manual to not install Samba 4 on a Verwaltungsserver. +++ This bug was initially created as a clone of Bug #34097 +++ The meta-package for administrative DC slaves (Verwaltungsserver) does not configure the selective replication for Samba 4 and does not disable DRS. This way such a host may mess up the LDPA/AD directories.
Hint has been added.
OK, looks good.
