Description Stefan Gohmann

We should do this in the join script:

+++ This bug was initially created as a clone of Bug #32245 +++

To re-join a Samba 4 Slave PDC (UCS@school school DC with Samba4) the following steps are necessary before the join can be started:

root@slave42:~# mv /var/lib/samba/private /var/lib/samba/private.BACKUP
root@slave42:~# mkdir -p /var/lib/samba/private

Actually what happens in this case is a re-provision. In my short test on a plain UCS DC Master samba 4.0.3 handled this fine (somewhat to my positive surprise) even without manually removing the existing sam.ldb. But: the S4 connector listener required a resync in my case, otherwise a lot of objects were missing in Samba4, especially the DNS data.  No idea yet why it works when the samba backend data is removed, maybe UCS@school Slave PDC is different here.
