Do not move to multi-master until you upgrade to a current OpenLDAP release. I also strongly advise using delta-syncrepl based MMR.After some digging on the current setup we have here, going to rebuild a new setup using 2.4.36. Any good howto's on MMR using delta-syncrepl ?
It's not much different than deploying standard syncrepl, and then adding in server IDs...
