Cyrus discrete murder issue : CREATE creates mail folder on frontend

[Tim Piessens]

Hi all,

I have created a murder cluster containing 1 update server, 1 frontend and 2 backends. 
Mail reading woks ok, also moving folders between backends. 
However when a client creates a new folder, it gets created on the frontend and not on a backend. 

I am using cyrus-imapd version 2.5.10 from debian testing
