I just did some more testing and I found some strange things.
Removing a user from the backendcluster replicates to the frontend just
fine.
Changing something in an existing user doesn't replicate to the frontend.
And creating a new user on the backend cluster doesn't replicate to the
frontend either.
So basicly deletions work fine, updates don't.

Does anyone have any clue here for me about what I'm missing?
