title: MVC3 mixed forms and Windows authentication
body: <p>I currently have an intranet site that is accessed by external customers. I therefore set this up using Forms Authentication. However the powers that be (my bosses) want all our domain users to not have to enter their username and password to access the site.</p>
  
  <p>I've done a bit or reading and everything seems to point to setting up a WinLogin.aspx page that you alter to use WindowAuthenthication and then redirect from there.</p>
  
  <p>I have a problem with this as I don't like the idea of putting an aspx form in my mvc application.</p>
  
  <p>Can anyone tell me how to achieve mixed authentication using a strictly MVC Controller/Action setup without a second application?</p>
  
  <p>NOTES: running MVC 3 on an IIS 7 box.</p>
