REST API with Windows Integrated security

Hi,

I found a way to call the REST API of Service Bus for Windows Server 1.1 by first calling the STS endpoint to get a OAuth token and then use it in the authorization token.

But the problem of that is that I need to pass a user/password in the STS url to get the authorization token (via $STS/Oauth).

Because the caller is an internal application, I want to use Windows Integrated Security. So I want to know how I can get an authorization token by using my Windows identity? Is it possible via the REST API?

Thanks.
