Hi, I don't know if it will perform well but, you can create an ACI on the top of the tree and negate writes for all, except the master 2 IP.

Hi List,
I would like to know if there is a cfg option in a multimaster replication ( 2 servers both accept read-writes) to prevent users/clients application writes to one of the master   without affecting the replication agreements.
my env 389-ds
Thank you
