Comment 15 for bug 1846789

This is currently working on Stein.

However, I have tried this on master (Train) with kolla-ansible 8.1.0.dev589 and it is still broken but less broken. The kolla-ansible deploy completes successfully, but horizon or keystone seem to be broken. Attempting to login through the horizon UI as admin results in "Unable to retrieve authorized projects."

Does that give us any insight into what fixed Stein?

Errors on master from keystone seem the same
