The original bug turned out to be a typo in a config file. Closing as
invalid, as this is going to be too confusing to change streams on what
the bug is.

If there is a second issue, please open as a second bug.

  2016-11-11 08:45:37.873 22626 WARNING keystonemiddleware.auth_token [-] Using the in-process token cache is deprecated as of the 4.2.0 release and may be removed in the 5.0.0 release or the 'O' development cycle. The in-process cache causes inconsistent results and high memory usage. When the feature is removed the auth_token middleware will not cache tokens by default which may result in performance issues. It is recommended to use  memcache for the auth_token token cache by setting the memcached_servers option.
