I am attempting to login to Microsoft Dynamic CRM from Linux. The CRM software is configured to use NTLM for authentication. I have installed Authen::NTLM and was still unable to authenticate to the CRM software but was able to authenticate to Sharepoint. I found this information about Negotiate (found at http://davenport.sourceforge.net/ntlm.html#ntlmHttpAuthentication) “With Windows 2000, Microsoft introduced the "Negotiate" HTTP authentication mechanism. While primarily aimed at providing a means of authenticating the user against Active Directory via Kerberos, it is backward-compatible with the NTLM scheme. When the Negotiate mechanism is used in "legacy" mode, the headers passed between the client and server are identical, except "Negotiate" (rather than "NTLM") is indicated as the mechanism name. “ and then installed LWP::Authen::Negotiate because the authentication had Negotiate before the authentication strings but have still been unable to successfully authenticate. Below is the script and result I receive (after I have authenticated to a domain). Does anyone have any advice on how to successfully authenticate to the CRM software? 
Script:

use LWP::Debug qw(+);
use LWP::UserAgent;

my $url = 'http:// xxxxx.xxx.xxx /';

# Set up the ntlm client and then the base64 encoded ntlm handshake me
+ssage
my $ua = new LWP::UserAgent(keep_alive=>1);
$ua->credentials(xxxxx.xxx.xxx:80', '', 'xxx\xxxxxxxxxxxxx' => 'xxxxxx
+xxxxxx');

#$request = GET $url;
my $request = new HTTP::Request GET => $url;
print "--Performing request now...-----------\n";
$response = $ua->request($request);
print "--Done with request-------------------\n";

#my $content = $response->content;
my $content = $response->as_string;
print $content . "\n";

if ($response->is_success) {print "It worked!->" . $response->code . "
+ " . $response->message . "\n"}
else {print "It didn't work!->" . $response->code . "\n"}


Result with only Authen::NTLM installed:
