I'm working on an ASP.net (VB) 2.0 site. What I'm trying to do is secure the site so that only certain Active Directory users have access to it. I do not want to require them to log in if possible. I also need to create a few pages to allow certain Active Directory users to define which other AD users have access. Is there a tutorial or site that is out there that can guide me through this? I'm swamped on other high-priority projects and haven't been able to research it much, but the deadline is quickly approaching. Any help or insite is greatly appreciated.
