 The actual values for these variables will need to be set depending on
 your situation, but in short:
 
-* ``identity_uri`` points to the Keystone Admin service. This information is
-  used by the middleware to actually query Keystone about the validity of the
-  authentication tokens. It is not necessary to append any Keystone API version
-  number to this URI.
-* The admin auth credentials (``admin_user``, ``admin_tenant_name``,
-  ``admin_password``) will be used to retrieve an admin token. That
-  token will be used to authorize user tokens behind the scenes.
 * ``auth_uri`` should point to a Keystone service from which users may
   retrieve tokens. This value is used in the `WWW-Authenticate` header that
   auth_token sends with any denial response.

   will get the Swift memcache from the request environment.
