Windows authentication without a password

Hi,

Is it possible to authenticate the user on Windows without entering the password?

Our script uses LWP and is talking to a webserver that requires authentication. The code is as follows:

# Perl code
my $ua = LWP::UserAgent->new(keep_alive => 1);
$ua->credentials(URI->new($url)->host_port, '', $USER, $PASS ) if $USER and $PASS;
my $resp = $ua->request( GET $url );

Now, it's failing as we don't have the $PASS stored in the script. The webserver team have advised us to use the equivalent of .NET's "credential cache":

// C# code
var webRequest = WebRequest.Create(mDownloadUrl);
webRequest.PreAuthenticate = true;
webRequest.Credentials = CredentialCache.DefaultCredentials;
...

Can this be achieved with LWP? Should perhaps the NTLM module (LWP::Authen::Ntlm) be of help here?

Thanks,
Sam
