CGI Page and REMOTE_USER environment variable

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I have following code which tries to read the REMOTE_USER environment variable passed by IE to the server, but it's not working:
use strict; use warnings; use CGI; my $q = CGI->new(); my $UserID = $ENV{"REMOTE_USER"}; print $q->header(); if($UserID){ print "User:<b>$UserID</b>"; }
The apache log shows
[error] Bad/Missing NTLM/Basic Authorization Header for /testarea/test [6275] AuthenNTLM: timed outwhile waiting for lock (key = 23754)
Anyone has some sugestion how to make this simple script work, or where to start debug?

    I don't do any CGI or WWW stuff in perl, but a brief review of the CGI docs indicates that you can use the remote_user() method to get the remote user's name. As I see it, you're trying to access the environment variable REMOTE_USER on the server.

    Also, the log shows a basic authentication problem, so you may be having trouble a bit before your code gets a chance to do much. I think I'd track down one of the CGI tutorials, or investigate one of the newer perl WWW frameworks that people are talking about.


    When your only tool is a hammer, all problems look like your thumb.

      my $q = CGI->new(); #my $UserID = $ENV{"REMOTE_USER"}; my $UserID = $q->remote_user(); print $q->header(); if($UserID){ print "User:<b>$UserID</b>"; }
      I get nothing in the page and the same error in the logs.

        It works for me (with shebang) on IE and Firefox.

        Smells like Apache2-AuthenNTLM

    CGI doesn't have much to do with AuthenNTLM, whatever software is responsible for that NTLM stuff is where the problem lies

    The error message your seeing is totally unrelated to the code of this script. In fact you'll probably see it for any script. Look for the cause outside of this small world that you're currently looking at.
