Yes. It was simply a standard Zimbra MMR deployment.

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
I'd like to follow up on this discussion, sorry if I've taken so long to reply.
First, I'd like to thank all that have commented so far, much appreciated.
I have a few more questions because some sort of un-easiness about my setup has
crept up in view of the different comments that have been written so far.
Right now I have 2 Debian Stretch 9.5 servers running 2.4.46 from the stretch
backports. Servers are in a MMR setup, using syncrepl for replication (NOT
delta-syncrepl), with a LMDB backend.
The intent is to use the directory as a users authentication repository for a
100+ workstations-- with what I said above, would such a setup considered safe?
Am I asking for trouble down the road with version 2.4.46?
Finally, should I rather consider the LTB project for Debian OpenLDAP as been
mentioned in some other threads rather than using the Debian backports? I'm a
bit reluctant to roll my own packaging from source.
Sorry for the very naive questions, I'm still fairly new to OpenLDAP!
