That WARNING above is unfortunately misleading in this case. The provider's
config parsing needs to be updated to understand that domain-name is a new
optional field (the field is still processed despite the warning).

But it doesn't indicate the cause of the failure. Perhaps only keystone 2 is
supported by the openstack cloud in use. The error message would be better if it
indicated the cause of failure.
