Perhaps I should restate my problem, as I think perhaps we still have<br>
crossed wires:<br>
<br>
- Certain configurations of Heat *only* work with v3 tokens, because we<br>
create users in a non-default domain<br>
- Current devstack still configures versioned endpoints, with v2.0 keystone<br>
- Heat breaks in some circumstances on current devstack because of this.<br>
- Adding auth_version='v3.0' to the auth_token section of heat.conf fixes<br>
the problem.<br>
<br>
So, back in March, client changes were promised to fix this problem, and<br>
now, in July, they still have not - do I revive my patch, or are fixes for<br>
this really imminent this time?<br>
<br>
Basically I need the auth_token middleware to accept a v3 token for a user<br>
in a non-default domain, e.g validate it *always* with the v3 API not v2.0,<br>
even if the endpoint is still configured versioned to v2.0.<br>
<br>
Sorry to labour the point, but it's frustrating to see this still broken<br>
so long after I proposed a fix and it was rejected.<br>

<div>I assume you mean switch over to keystone middleware project [0], not switch over to keystone v3. Based on [1] my understanding is no changes to nova are needed to use the v2 compatible parts of the v3 API, But are changes needed to support domains or is this not a problem because the auth middleware uses uuids for user_id and project_id, so nova doesn't need to have any concept of domains? Are any nova changes needed to support the v3 API?</div>
<div><br></div><div><br></div><div>Switching over the default to v3 in the middleware doesn't test nova + v3 user tokens, tempest nova tests don't generate v3 user tokens (although I hear there is an experimental job to do this). So you are testing that moving the middleware to v3 but accepting v2 API user tokens works. But what happens if someone tries to use a the non-default domain? Or using other v3 only features? Switching over to v3 for the middleware without actually testing any v3 user facing features sounds like a big testing gap.</div>

There are some things that need to get through gate and then we will do the release of keystonemiddleware that should address your problem here.
