Comment 1 for bug 1297880

heat.common.auth_url contains the middleware filter which adds the auth url to the request context, either from the request or from heat.conf.

As an aside, heat-standalone running on a single OpenStack should work, but multicloud development has stalled until blueprint multi-region-support has landed, since multi-cloud is an extension of multi-region and we want to get multi-region working correctly first.
