I have an ASP.NET (3.5) application that uses Windows Authentication. Now I want to set authoritzation based on ASP.Net roles. I used the ASP.NET Configuration tool to create the roles and I know how to specify that a role has authority to a page. What I don't know how to do is add Active Directory users to the roles. Is there a way to do this? Can it be done using the ASP.Net Configuration tool?
