There are configuration differences (see the Admin Guide for the needed
snippets; N-Way requires MirrorMode and then some) but yes, MirrorMode
requires writes to go to only one node at a time.

I've re-red those sections of docs two more times, still don't see the
difference

There is no configuration difference at this point. I think there was one initially ages ago. The only difference between MMR and mirror-mode MMR is that in the latter case, writes only go to a single master instead of any master in the cluster.

In all cases, I strongly advise using delta-syncrepl based MMR with the most current OpenLDAP release (2.4.33).
