Comment 1 for bug 1885724

Couple of hints to proceed:
1. It's strange that authentication fails so late when Heat stack is being created. During the initialization Shaker verifies credentials by requesting a token from Keystone (https://opendev.org/performa/shaker/src/branch/master/shaker/openstack/clients/openstack.py#L67). Is there a message 'Connection to OpenStack is initialized' in Shaker logs?
2. There is a message from keystone log '2020-06-30 16:48:51.849 30 WARNING keystone.auth.plugins.core [req-a7c5e591-5a10-4587-9061-e51e5f4ca07d - - - - -] User is disabled:' -- is it expected that the user is disabled? Could it be that the user does not have some of permissions (e.g. to create Heat stack)?
