title: Configuring WebAPI for Forms Authentication
body: <p>I'm working with webApi and trying to implement forms auth.  My application is using simpleMembership.  For some reason my controllers are reverting to my windows credentials to check and see if a request is authenticated, when it should just be using simpleMembership against my app's database:</p>

  <p>I've disabled windows and anonymous auth in the app and in my applicationhost config file... what else needs to be done? </p>
