    Remarks
    Implement a ISignOnHandler to handle authentication requests for federated feature services (that are secured). Within the SignOnHandler, call SignInWithCredentials using the provided portal URI passed in to your callback via the ISignOnHandler.GenerateCredentials callback. It is your responsiblity to provide the relevant username and password for authentication against the portal or arcgis online. Your callback will be invoked anytime the underlying system requires a credential for a portal or online. Note: a feature service db will attempt authentication twice (assuming the first attempt failed).
    To remove your callback handler, set the sign on handler to null, i.e. ArcGISSignOn.Instance.SetSignonHandler(null);
