I'm a little bit out of my league here with a current project I've been tasked with.

I've made a website and database and put it on our internal network so it can be accessed, updated, and viewed. The next part is that certain pages on the website need to be visible only to specific users. I'm really not sure where to go now, the requirements are

- Usernames and passwords be retrieved from the Active Directory

- An interface allowing a superadmin to go in and set the users provided by Active Directory at various levels of authorization in the website

I had started to implement a username/password solution using the ASP.NET provided SQL roles and user management, but that solution was determined to be unacceptable, so I'm at the end of my rope
