The question is about CGI environment variables and perl CGI.pm for that matter, so he should be able to ask this list for help. Also, this is not server specific. It's same on Apache and IIS.
The remote_user() or user_name() is only set when the visitor is required by the web server to authenticate using a login name and password. So if your script or the URL the visitor ask for is not password protected, then the remote_user() or user_name() will return undefined. Refer to perldoc CGI for more about remote_user() or http://www.cgi101.com/book/ch3/text.html for CGI environment variable. I hop e you will get answer to most of your problems.
