 * ``auth_host``: (required) the host providing the keystone service API endpoint
   for validating and requesting tokens
+* ``auth_port``: (optional, default `35357`) the port used to validate tokens
+* ``auth_protocol``: (optional, default `https`)
+* ``auth_uri``: (optional, defaults to
+  `auth_protocol`://`auth_host`:`auth_port`)
+* ``auth_version``: API version of the admin Identity API endpoint
+* ``delay_auth_decision``: (optional, default `0`) (off). If on, the middleware
+  will not reject invalid auth requests, but will delegate that decision to
+  downstream WSGI components.
+* ``http_connect_timeout``: (optional) Request timeout value for communicating
+  with Identity API server.
+* ``http_request_max_retries``: (default 3) How many times are we trying to
+  reconnect when communicating with Identity API Server.
+* ``http_handler``: (optional) Allows to pass in the name of a fake
+  http_handler callback function used instead of `httplib.HTTPConnection` or
+  `httplib.HTTPSConnection`. Useful for unit testing where network is not
+  available.
+
 * ``admin_token``: either this or the following three options are required. If
   set, this is a single shared secret with the keystone configuration used to
   validate tokens.

+* ``token_cache_time``: (default 300) In order to prevent excessive requests

+  Keystone API returns. This is only valid if memcache_servers s defined. Set
+  to -1 to disable caching completely.
+* ``memcache_security_strategy``: (optional) if defined, indicate whether token
+  data should be authenticated or authenticated and encrypted. Acceptable
+  values are MAC or ENCRYPT.  If MAC, token data is authenticated (with HMAC)
+  in the cache. If ENCRYPT, token data is encrypted and authenticated in the

 * ``include_service_catalog``: (optional, default `True`) Indicate whether to

   service catalog on token validation and will not set the X-Service-Catalog
   header.
+* ``enforce_token_bind``: (default ``permissive``) Used to control the use and

+  "permissive" (default) to validate binding information if the bind type is of
+  a form known to the server and ignore it if not. "strict" like "permissive"
+  but if the bind type is unknown the token will be rejected. "required" any
+  form of token binding is needed to be allowed. Finally the name of a binding
