As far as I can see there is no difference in configuration. The only
distinction I can see is the "use case", as N-Way supposed to accept
writes on all Masters, but Mirror only on one at a time.
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).
Quanah, thanks alot, this clears up things.
Maybe somebody comment on number 4 from my initial post:
4. In Mirror mode, can I use UpdateRef on one mirror to direct writes
to another so proxy/balancer will become not required?
