Comment 7 for bug 1885724

So it looks like the stack is created successfully, which means that user is authenticated in Heat and has enough privileges. But then the user is not authenticated when Heat tries to create certain resources.

Could you check some more things:
 * Can Heat create any stacks when the command is issued from command line?
 * At which resource does stack creation fail? What if you try to create Heat stack with that resource from the command line? (you can refer to the template of Shaker's stack at https://opendev.org/performa/shaker/src/branch/master/shaker/scenarios/openstack/l2.hot or you can keep the stack created by Shaker by providing --nocleanup-on-exit parameter)
