title: Is there a good approach to combine Windows authentication and Forms authentication in ASP.NET MVC?
body: <p>I have a scenario where some users are going to be required to log into an application (forms authentication), while others will be authenticated via Windows authentication.  To determine if a user is required to login, I'll be looking up permissions for the Window AD users using a custom role/permission implementation.  </p>
  
  <p>In ASP.NET MVC, you can set the authentication configuration to either "Windows" or "Forms authentication".  I know this could be done by creating two applications but I don't like that option  </p>
  
  <p>I'm about to try to convince my boss that forcing everyone to login will make our lives a lot simpler but I thought I better check to see if there any good options out there.   I couldn't find one possible solution for ASP.NET MVC.  I'm using version 2.</p>
  
  <p>Any ideas?</p>
