Hi, We use the 389 Directory Server version 1.4.2.15. In the documentation of the Red Hat Directory Server it says, as many as 20 masters are supported in an MMR. It sounds to be a hardcoded limitation defined to avoid overloaded servers and network. Shouldn't it be depending on the MMR topology, i.e. rather on the total number of replication agreements within the whole scenario? Or does "20 masters" indeed mean that the limitation of the MMR topology is the number of 380 replication agreements as shown in the "fully connected mesh" scenario (https://access.redhat.com/documentation/en-us/red_hat_directory_server/10...) with 20 masters and 20x19 replication agreements? Is there someone who possibly has experience with scenarios of more than 20 master servers? Thanks, Eugen
