Recently I decided to remove deprecated parameters from keystone_authtoken mistral config and replace them with recommended function of devstack [1]. In doing so, I discovered a strange behavior of configuration mechanism, and specifically parameters auth_uri and auth_url. 1. The parameter auth_url is not included in the list of the middleware parameters, there is auth_uri only [2]. Nevertheless, it must be present, because it's required by identity plugin [3]. Attempts to remove or replace it with the recommended auth_uri result with these stacktraces [4] 2. Even if auth_url is set, it can't be used later, because it is not registered in oslo_config [5] So I would like to get an advise from keystone team and understand what I should do in such cases. Official documentation doesn't add clarity on the matter because it recommends to use auth_uri in some cases and auth_url in others. My suggestion is to add auth_url in the list of keystone authtoken middleware config options, so that the parameter can be used by the others.
