It seems like I am not the only one facing this problem.

Is this officially reported as a bug ?

I found out that when deleting an entry on the master I added it to, it is removed only on this master and deleting is not replicated until I make some other operation on the other master. Seems like the delete is "queued".

When deleting an entry on the "other" master (not the one I added the entry to), the delete works fine and is correctly replicated.

Anyone to help me with N-Way Multi-Master replication ?

Hello Adrien,

I have the same problem deleting entries on N-Way MultiMaster.

Did you resolved this problem ?

Best Regards.

OK, But then what did I do wrong ? delete an entry shouldn't be a problem with N-Way Multi-Master replication ? should it ?

Here is how I have setup-ed my masters :

Did I miss something ? Has anyone tested N-way Multi-master replication & encountered the same problem as me ?

Hy everyone,

I have just tested the same procedure with OpenLDAP 2.4.13. The problem remains the same.

Did I miss something ? Is this supposed to be like this ?

I'm joining the modified script I'm using to setup both masters and the LDIF files I'm using to add and remove an entry (+ attributes).

I did not use access-log, is this supposed to work with N-Way Multi-Master replication ? I thought it was only used in case of Delta Synchronization/Replication.

Correct, delta-syncrepl and MMR are not currently supported together (that may change in the future).
