title: How to pass Windows Authentication credential from client to Web API service
body: <p>Inside my corporate environment, I have IIS7.5 hosting both a Web API service and a separate website which makes calls into that service via the RestSharp library.  Both are currently configured with Windows Authentication.  </p>
  
  <p>If I navigate to either one with a browser, I'm prompted to enter my windows credential, and everything works great... I get web pages that I want and the REST service spits out my data.  The part I'm struggling to figure out is how to use a single credential to authentication both.  I can't figure out how to either pass the Website's credential to the service (I tried impersonating but it didn't work), or to manually prompt the user for username/password and then authenticate them with "Windows".</p>
  
  <p>Help a noob out?</p>
