The answer is quite simple: do not use multimaster replication in a production environment. In most cases the requirement for multimaster replication is just based on poor directory design.
Dieter, I do not agree with that. You can't blame a user for using a feature. It is not marked as experimental anymore so people are going to use it. Once it fails you can't call them a "Poor Directory Designer" for using it.
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.
