I have a servlet running on Tomcat 4.0 which the users can get to from our intranet running on IIS. I know using Windows API calls, you can retreive usernames from IIS, Is there a way to get the username when they come to my servlet? I do not want to use Windows API and I do not want to use a popup login. Basically what I need to be able to do, is determine the user and then restrict access to certain links and properties of the servlet.. Thanks for any help
