The CephX security capabilities let you specify what uid/gid the client is allowed to operate as. Looks like http://docs.ceph.com/docs/master/cephfs/client-auth/ doesn't include that :/ but the syntax would just be "allow rw path=/foo uid=1 gids=1,2" That lets a specified client read and write data only within the "/foo" directory, and only while acting as user 1 with groups 1 and 2. -Greg _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
