Why logon twice?

When a user attempts to access a page on the server
they are asked to logon to the machine, and quite rightly
so, but whenever they click on a link that runs a Perl
script on that same machine, they are asked to logon
to localhost. Can anybody please tell me why this it?

Thanks.

What authentication method are you using for the perl script? Integrated?
If they enter their credentials, do they get in?

Thank you,
