The site I'm currently developing has a page where visitors can post updates to projects. There's a space for them to put in their login name, which is the same they use to log into the system (WinNT 4). I'd like to grab the login ID of who is signed into the computer so we'll know who really posted the update as well as who they say they are. I tried using CGI.auth_user, but that's coming up as not existing. Is there somewhere in the registry that I can snag this and if so, what would the CF code look like?
