Get `ICredentials` from Windows Authentication

Question

I'm using Windows Authentication.

I need to log into a service. It requires authentication using an ICredentials object, but would rather avoid asking for the user to enter their credentials again.

Is there a way to get the ICredentials from the currently logged in user?

The service is the TFS SDK.

Controller in MVC has a property User which is IPrincipal.

IPrincipal has an Identity property

http://msdn.microsoft.com/en-us/library/system.security.principal.iprincipal.identity%28v=vs.110%29.aspx

which is of type IIdentity

If you're using Windows Authentication the actual instance will be of type WindowsIdentity

Hopefully it will contain all the credential information you need.

Also, you might want to try:

Uri uri = new Uri("http://tempuri.org/");
ICredentials credentials = CredentialCache.DefaultNetworkCredentials;
NetworkCredential credential = credentials.GetCredential(uri, "Basic");
