If i can't use multi master with refreshandpersist then why its given at all. i was able to get replication working with same configuration in other testing environment, but with very less users 1m only.
I don't understand your statement/question. Delta-Syncrepl MMR uses refresh and persist, and it is the best option to use for replication in OpenLDAP. Particularly with multi-master replication.
