I am not blaming any user who has to implement multimaster
replication, at least this has not been my intention. If you want to
set up a partitioned or replicated directory you have to take a lot of
requirements into consideration, only to think about the number of
connections in a multimaster environment, (n *(n-1)).
Just name a network topology or a directory design requirement that is
dependend on multimaster replication. I personally know only of one
directory where multimaster with 10 providers had to be
implemented. On the other hand I do know of directories with up to 150
consumers connecting to one provider.
