Hi all,

I am experimenting with different replication configurations and I may have a rather silly question.

Are any differences between a MirrorMode and 2 node Multi-Master replication?

...

From configuration point of view they look like the same, but are

they?

Reading the Admin guide I see that on the MirrorMode configuration example there are no syncpro overlay settings, shouldn't be?

This explains it:

http://www.openldap.org/doc/admin24/replication.html#MirrorMode%20replicatio...

If I understood it correctly, on N-way Multi-Master replication any member can accept write operations while on MirrorMode only must|should accept write operations.

I had a MirrorMode configured and I was able to send writes on both servers and each server was replicating the changes without problems. The test which I did was very simple, first add/remove an entry on the first and then add/remove an entry on the second.

So, the above test made to wonder about the differences between MirrorMode and 2-way mulit-master.

what is the reason on a MirrorMode replication to force all write operations to one of the members of the replication?

BTW, what about the syncpro overlay settings which are not part of the MirrorMode configuration example?

Thanks, Pavlos
