While I'm not sure what the cause of the HTTP Unauthorized exception
might be (perhaps turning on debugging options might help narrow it
down?), I suspect you may have an easier time developing against the
unified OpenStackSDK rather than the individual per-service client
libraries. For some simple examples of configuring and connecting,
see the Getting Started chapter:

Hope that helps!
