Theoretically, it's supposed to work so that consumers can point to more than one master in an MMR setup, but my experience didn't match that (<http://www.openldap.org/its/index.cgi/?findid=8373>).There's no config in ITS#8373. But you mention accesslog DB. Does that mean your setup used delta-syncrepl?
Yes. It was simply a standard Zimbra MMR deployment.
If yes, does that issue also apply to normal syncrepl?
No idea. I generally consider "normal" syncrepl unsafe as using it can lead to data loss. I use delta-syncrepl exclusively because of this, with a focus on eliminating all scnearios in which it might fall back to "normal" syncrepl. (See <http://www.openldap.org/its/index.cgi/?findid=8125> for example).
