Comment 11 for bug 1458532

Ok, some updates related to issue.
It turns out that creat_and_delete_stack with volume is executing more than 1 hour.
You can see it in run_rally-debug.log:
http://paste.openstack.org/show/262935/.
That's why heat failed with authorization failed and after that cinder failed with authorization error.
It seems that heat have some problems with volume deletion because stack is hanging when trying to delete volume:

I asked Ivan Kolodyazny to analyze the root cause.
Waiting for feedback from him.
