Hello, Quanah,

I do not understand the irritation. I have read the changes.html file and
I do not see any entry saying "fixed Multi-Master replication as it was

The truth that I have subscribed to this list because of seeing a similar
problem like Guillaume reported and I did have a look at the changelog.

Is OpenLDAP THAT broken below 2.4.32?

No such text would ever appear in the changes log. However, someone who has some basic reading skills can probably discern the following fixes are likely to impact their installation. Particularly the fix specific to MMR in 2.4.24. Given the fact that MMR uses syncrepl, one then has to track all the fixes made to syncrpel/syncprov as well.
