``foo``, radosgw is able to transparently discern them by their tenant
prefix.
+It is also possible to limit the effects of implicit tenants
+to only apply to swift or s3, by setting ``rgw keystone implicit tenants``
+to either ``s3`` or ``swift``. This will likely primarily
+be of use to users who had previously used implicit tenants
+with older versions of ceph, where implicit tenants
+only applied to the swift protocol.
