Yes, I do receive the "INVALID_LOGIN" response. Here is the full output with the debugging:

This was run with perl v5.14.3 on 64-bit Linux. Since the cert verification will either pass or fail regardless of the payload, you could try an even simpler script such as this:

use strict;
use warnings;

use LWP::UserAgent;
use Mozilla::CA;
my $ua = LWP::UserAgent->new(
        ssl_opts => {
                verify_hostname => 1,
                SSL_ca_file => Mozilla::CA::SSL_ca_file()
        }) or die;
my $url = $ARGV[0] || 'https://login.salesforce.com/';
my $res = $ua->get($url);
print $res->code . "\n";

exit;

You can then run this with any number of known, good URLs (eg: https://www.google.com/ or https://metacpan.org/ ) to see if any of them pass verification.

Good luck.
