Correct, however Red Hat also tested up to 60 for FreeIPA. Certainly I know there is a deployment in the world that has scaled up past 1000 servers. Generally once you get past say 8 servers, you need to think about your replication topology and how the data will flow. The largest sites I know tend to go to maximum 8 write-accepting servers, and then replicate to N hubs and replicas that are read only past that for the best performance and reliability. > > Regards, > > > Paul M.
