ASP.NET Mixed Mode Authentication v2

Dear all, I need a sample web application which supports following authentication methods against Microsoft Active Directory: * Windows Integrated Authentication * Forms Authentication The coding needs to be done using: * Microsoft Visual Studio 2008 * ASP.NET in VB mode * ASP.NET Framework v2 * Webserver is IIS v6 Solution should work with following browsers and versions: * Internet Explorer v6+ (must) * Internet Explorer v7+ (must) * Firefox v3+ (must) * Safari (nice to have) Workflow: 1. User opens the default page 2. If user is logged in through an Active Directory domain, the credentials are used for logging in to the site. 3. If user is anonymous, then the request is redirected to a login form. The solution: * ...must work without popup's, asking for credentials. The login need to work seemlessly, i.e. if request not coming from an Active Directory authenticated user simply the login form is displayed. * ...should use preferably an http module to handle the incoming requests and decide whether to let the user in or display the login form. * ...must run under a virtual directory on the webserver, i.e. http://webserver/testpage/[login to view URL] Best Regards, Ibrahim
