then again i think, i need Authorization and not Authentication, so doesn't i need something totally different (than following)?

i was trying to do that, and its hard. The LWP:Authen::Negotiate is not available for windows. So looking at the source code, it is based on a modul called GSSAPI, which is not available for windows too. So which windows alternative is there for GSSAPI?

I found Authen::SASL-Perl-Ntlm, if i can use that, how would my use of it look like? since i got no username or pasword?

   use Authen::SASL qw(Perl);

    $sasl = Authen::SASL->new(
        mechanism => 'NTLM',
        callback  => {
          #  user => $username, # just to leave it empty??
          #  pass => $password, ??
        },
    );

    $client = $sasl->client_new(...); #what to set here? 
    $client->client_start;
    $client->client_step('');
    $client->client_step($challenge);

could that really work?
