Comment 10 for bug 1850656

Settings:
[oslo_policy]
enforce_scope = True

GET /v3/services
identity:list_services

"openstack_auth": {
  "auth_url": "http://192.0.2.10:35357",
  "username": "admin",
  "password": "9PJVm6kJI1k00JgNzhXpRAosMAXBkIqSSmDYDwR3"
}

Error:
keystoneauth1.exceptions.http.BadRequest: Expecting to find domain in user. The server could not comply with the request since it is either malformed or otherwise incorrect. The client is assumed to be in error. (HTTP 400) (Request-ID: req-ea92e74e-2cf1-4524-9c78-a02f24a180a1)

Goal:
Getting auth into scope 'system'. I can not figure out how to do this.
