Description Arvid Requate

samba-ad-dc restart during server password change breaks DRS replication. We need to do a /etc/init.d/samba restart instead.




+++ This bug was initially created as a clone of Bug #47634 +++

Restarting only samba-ad-dc breaks drs replication in Samba 4.6.15 (UCS 4.2)

For example after

  /etc/init.d/samba-ad-dc restart


the command "samba-tool drs showrepl" fails:

ERROR(runtime): DsReplicaGetInfo of type 0 failed - (-1073610699, 'The operation cannot be performed.')

The same happens for restarts with "systemctl" and "service".


After a "/etc/init.d/samba restart" it works again.

             not just the AD/DC component

seems that invoke-rc.d samba restart does nothing, use /etc/init.d/samba restart instead

Comment 4 Arvid Requate

06019a9966 | run /etc/init.d/samba instead of "service samba"
             and "invoke-rc.d samba"
