The short answer is that the system has run your Perl program, as shown by the
USERNAME environment variable. No one has logged in and run the program - it's
being run by IIS itself in response to an HTTP request from a remote client.
What you need to know is the identity of the remote user who made that request.
If you have authorization configured on your server the value you need is in
$ENV{LOGIN_USER}
or possibly
$ENV{AUTH_USER}
but if those values are empty then you cannot tell who is logged in at the
remote computer.
