I have opened: http://tracker.ceph.com/issues/15783 fuse kernel does not have ACL support. To use ACL, you need to add "--fuse_default_permission=0 --client_acl_type=posix_acl" options to ceph-fuse. The '--fuse_default_permission=0' option disables kernel file permission check and let ceph-fuse do the check.
