[Kazuto Sakurai]

At Identity API v3 (CURRENT),
  http://developer.openstack.org/api-ref-identity-v3.html#authenticate

error response codes of the Tokens Authenticate API are written as follows:
--------------------------------------------------
Error response codes:
  Unauthorized (401), ##
  Bad Request (400),
  Unauthorized (401), ##
  Forbidden (403),
  Method Not Allowed (405),
  Request Entity Too Large (413),
  Service Unavailable (503),
  Not Found (404)
--------------------------------------------------
Unauthorized (401) codes (pointed by ##) are duplicated.
