Comment 2 for bug 1801913

Thanks for the report. I've proposed https://review.openstack.org/616509 with the fix to Packstack, and also https://review.openstack.org/616502 to puppet-magnum, to solve the mistake in the deprecation.

I've tested the fix locally, and magnum cluster-list now behaves as it should. Our test coverage in the gate is very limited for magnum, so if you find any other issue please do not hesitate to open more bugs :).

While the fix is merged, you can test it locally by adding "/v3" to the www_authenticate_uri parameter in /etc/magnum.conf, and then restarting the openstack-magnum-conductor and openstack-magnum-api services.
