Not all references of 'auth_uri' have been removed from openstack projects when we deprecated 'auth_uri' to bring 'www_authenticate_uri'

[Abhishek Sharma M]

As part of https://review.openstack.org/#/c/508522/, we replaced 'auth_uri' middleware parameter with 'www_authenticate_uri' parameter to avoid confusion between 'auth_uri' & 'auth_url' parameters.

However, the changes were made just in openstack/keystonemiddleware project & all the other references to 'auth_uri' in other openstack projects were not taken care of.

We are concerned that if we switch to 'www_authenticate_uri' parameter in our [keystone_authtoken] section, these 'auth_uri' references might create problems. So, it will be better if community completely gets rid of 'auth_uri'.

Some of the files in which I could find 'auth_uri' references are below:

https://github.com/openstack/cinder/blob/master/cinder/quota_utils.py
https://github.com/openstack/cinder/blob/master/cinder/tests/unit/api/contrib/test_quotas.py
https://github.com/openstack/cinder/blob/master/cinder/tests/unit/volume/drivers/nexenta/test_nexenta5_jsonrpc.py
https://github.com/openstack/cinder/blob/master/cinder/tests/unit/conf_fixture.py
https://github.com/openstack/cinder/blob/master/cinder/tests/unit/test_quota_utils.py
https://github.com/openstack/cinder/blob/master/cinder/tests/unit/test_quota.py
https://github.com/openstack/cinder/blob/master/cinder/tests/functional/api/client.py
https://github.com/openstack/nova/blob/stable/queens/nova/tests/functional/api/client.py
https://github.com/openstack/nova/blob/stable/queens/nova/tests/unit/api/openstack/placement/test_deploy.py

Apart from these also grep for 'auth_uri' in mistralclient & networking_infoblox prjects.
Not all files would require the change as some of them just use auth_uri as variable name. I am not sure if this needs to be taken care by keystonemiddleware team or respective project teams, as of now assigning to keystonemiddleware. Please change accordingly.

yeah, it's a good reminder. The projects who use keystonemiddleware should pay attention.

After checking Cinder code, I think it's a wrong usage. Cinder should use auth_url, not auth_uri.

It might help to associate projects that need assistance moving to www_authenticate_uri to this bug report.

Looks like there are other projects still relying on auth_uri [0]. Keeping this open since it's a relatively good low-hanging-fruit bug and something we should try and correct in other services.
