Title:
  Fernet tokens and Federated Identities result in token scope failures

Status in Keystone:
  Fix Released

Bug description:
  When keystone is configured to use fernet tokens and also configured
  to be a SP for an external IDP then the token data received by nova
  and other services appear to not contain the right information,
  resulting in errors from nova-api-os-compute such as:

  Returning 400 to user: Malformed request URL: URL's project_id
  '69f5cff441e04554b285d7772630dec1' doesn't match Context's project_id
  'None'

  When keystone is switched to use uuid tokens, then everything works as
  expected.

  Further debugging of the request to the nova api shows:

  'HTTP_X_USER_DOMAIN_NAME': None,
  'HTTP_X_DOMAIN_ID': None,
  'HTTP_X_PROJECT_DOMAIN_ID': None,
  'HTTP_X_ROLES': '',
  'HTTP_X_TENANT_ID': None,
  'HTTP_X_PROJECT_DOMAIN_NAME': None,
  'HTTP_X_TENANT': None,
  'HTTP_X_USER': u'S-1-5-21-2917001131-1385516553-613696311-1108',
  'HTTP_X_USER_DOMAIN_ID': None,
  'HTTP_X_AUTH_PROJECT_ID': '69f5cff441e04554b285d7772630dec1',
  'HTTP_X_DOMAIN_NAME': None,
  'HTTP_X_PROJECT_NAME': None,
  'HTTP_X_PROJECT_ID': None,
  'HTTP_X_USER_NAME': u'S-1-5-21-2917001131-1385516553-613696311-1108'

  Comparing the interaction of nova-api-os-compute with keystone for the
  token validation between an internal user and a federated user, the
  following is seen:

  The data structures that come back from keystone are clearly quite
  different.

  Keystone is configured as a Shibboleth SP with a trust relationship
  between it and an ADFS IdP.

  The mapping rules are setup as follows - note that the user's
  default_project_id was added in an attempt to see whether it helped.
  It does seem to reflect in the HTTP_X_AUTH_PROJECT_ID at the nova api
  as shown above.

  [
    {
      "local": [
        {
          "user": {
            "id": "{0}",
            "name": "{1}_{2}",
            "email": "{3}",
            "default_project_id": "69f5cff441e04554b285d7772630dec1"
          }
        }
      ],
      "remote": [
        {
          "type": "primarysid"
        },
        {
          "type": "givenname"
        },
        {
          "type": "surname"
        },
        {
          "type": "upn"
        }
      ]
    },
    {
      "local": [
        {
          "group": {
            "name": "fedgroup",
            "domain": { "name": "Default" }
          }
        }
      ],
      "remote": [
        {
          "type": "Group",
          "any_one_of": [
            "Domain Users"
          ]
        }
      ]
    }
  ]

  A Shibboleth session shows the following attributes available from the
  IdP:
