I'm trying to create an application that mixes windows authentication with forms authentication. The idea is simple: whenever the browser is able to use NTLM and the user has permissions, then he should be automatically logged in. When that doesn't happen, the user must be redirected to a page that shows a login form. I've found an old article (http://mvolo.com/iis-70-twolevel-authentication-with-forms-authentication-and-windows-authentication/) and I've also found a sample online (https://github.com/patuww/P2000DemonstrationProjects/tree/master/MultiAuthExample) which should be able to solve my problem.
Unfortunately, it's not working and I was wondering if there's any more info about this.
Thanks.
Luis
