[ceph-users] CephFS no permissions for subdir

Hi! Is it possible and if yes how to remove any permission to a subdir for a user. I'd tried to make this: ceph auth caps client.XYZ mon 'allow r' mds 'allow r, allow rws path=/XYZ, allow path=/ABC' osd 'allow rw pool=cephfs_data' but got: Error EINVAL: mds capability parse failed, stopped at ', allow path=/ABC' of 'allow r, allow rws path=/XYZ, allow path=/ABC' Thanks Lars
