mx.IsAuthenticated returns true, nonetheless - user is not logged in. Perhaps a better means of checking whether the user is Authenticated is required

Nobody has claimed this yet.

Reproduce the failing policy update and compare mx.IsAuthenticated with the _mx_api call that raises the “User is not logged in” error. Start with MxConnection.py and WebServiceCustomPolicy.py, especially _mx_api and _update_web_service_custom_policy. Done means the authentication check reliably reflects whether the subsequent API operation can run, with a test covering this mismatch.
