tl;dr keystone.middleware.auth_token is deprecated (and currently broken)
in favor of keystoneclient.middleware.auth_token

During grizzly we moved auth_token from keystone to keystoneclient, and
provided a bit of backwards compatibility for configurations still using
keystone.middleware.auth_token by having keystone import auth_token from

Unfortunately that backwards compatibility is now broken and being tracked
in an RC-blocking bug:


I described the root cause of the problem in comment #12:


I've proposed two fixes based on markmc's comments in that bug.

A) Drop support for keystone.middleware.auth_token:


B) Ignore the exception described in the bug and log a warning:


Neither solution is ideal IMO but we need to fix this for RC1; feedback &
alternative solutions welcome!
