The next stable release will have cephx authentication enabled by default. We will probably do it in the next development release (v0.53) to work out any upgrade kinks well before that. The process for setting up teh authentication keys on an existing cluster is at http://ceph.com/docs/master/cluster-ops/authentication/ This needs a few eyeballs to make sure the upgrade process makes sense...
