Is there any way to use the current device account on the Surface Hub as credentials to authenticate in remote services hosted on IIS that use Windows authentication in the UWP app?
Currently we're using the default credentials supported by System.Net.HttpClient, and it works fine on the desktop, but the Hub sends wrong credentials and it results in 401 Unauthorized response.
Both the Hub and the service are joined to the AD Domain.
Please make sure that you have added the Enterprise Authentication and Private Networks(Client & Server) capabilities in your app manifest.
