Subject:	Re: [Openstack] HTTP_X_SERVICE_CATALOG endpoints_links



The environment variables that auth_token sets are documented in the
module's docstring:
https://github.com/openstack/keystone/blob/master/keystone/middleware/auth_token.py

As these variables are the defined interface for any projects consuming
authentication services from middleware, it's safe to say they'll be
supported be supported by any variations of auth_token, and will either
continue to be supported or carefully deprecated.

Speaking of, there are currently three headers that were deprecated prior
to the release of essex (i.e. they were documented as deprecated in both
essex and folsom), and could be reviewed for removal in grizzly
(HTTP_X_USER, HTTP_X_ROLE, HTTP_X_TENANT).

  After a user gets authenticated, each following request will have a

  links, can any one tell me if it is safe to use the information contained
  in the header to get the various end points from a filter in the
  pipeline? Notice this header is set in the keystone, any other
  implementation of keystone may choose not to include the information in
  the header, can anyone tell me putting the endpoints in the headers is
  required by any implementation like keystone for authentication?

  Thanks.
