You stated previously that you are in 4-way MMR. It's not valid to have a serverID of 0 in an MMR environment (See http://www.openldap.org/its/index.cgi/?findid=8635).

Well now, that's quite a fresh ITS 8-/. I'm guessing quite a few people have serverID's of 0 in their replicated environments, as I don't know that I've ever seen that information before. What are the ramifications of having a server with an ID of 0 in a replicated environment? What is the procedure for remediating the issue? Is it as simple as shutting down that server, updating the configuration to have a serverID of 4 and restarting it? Or does the database need to be stripped of all CSN's which have an ID of 0 via slapcat, grep -v, and then slapadd with the -w option on the master and then reloading from ldif on all the replicas?
