Description Arvid Requate

2018-05-22 19:25:53 CEST

In case a customer has more than one Samba/AD domain controller and he reverts one of them to an earlier VM snapshot (or restores from backup), the AD DRS replication mechanism is broken: All remaining DCs stop receiving changes from the reverted DC until his "highestCommittedUSN" has reached the number that it head before the revert happened.

Since these cases are not very obvious every day error conditions, we should have a Nagios check for that.
