Hi, I´ve tried now many different ways, to authenticate against a web-server, i found on the web. One of them is this: 
use HTTP::Request::Common;
use LWP::Debug qw(+);
use strict;
use warnings;

my $url = "http://********.com/MBSDKService/MsgSDK.asmx?WSDL.RunQuery?
+queryName=physical_windows_servers_itop_query";

my $ua = new LWP::UserAgent(keep_alive => 1);

$ua->credentials('http://********.com/MBSDKService/MsgSDK.asmx?WSDL', 
+'', '**USERNAME***', '***PASSWORD*****');

my $req = GET  $url;
print "--Peforming request now...---------\n";

my $res = $ua->request($req);
if ($res->is_success) {
    print $res->content;
} else {
    print "Error: " . $res->status_line . "\n";
    print $res->headers()->as_string(), "\n";
}
exit 0;

If it is still unclear what i want: I want to connect to the LandDesk Web Service. (This is the documentation for PowerShell: Documentation) Therefore i need to authenticate and do an Http Post / Get, that i can get a XML file back. Hopefully you understand, what i want. I will be so thankful, if you can help me :) Kind regards Jan
