In doing patch [1], A suggestion is submitted that we should return 400 (bad Request) instead of 403 (Forbidden) I take a look at [2], seems 400 is not a good candidate because 'The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications. ' may be a 409 (conflict) error if we really don't think 403 is a good one? Thanks [1] https://review.openstack.org/#/c/173985/ [2] http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html Best Regards!
