NAME
       LWP::Authen::Ntlm - Library for enabling NTLM authentication (Microsoft) in LWP

SYNOPSIS
	use LWP::UserAgent;
	use HTTP::Request::Common;
	my $url = 'http://www.company.com/protected_page.html';

	# Set up the ntlm client and then the base64 encoded ntlm handshake message
	my $ua = LWP::UserAgent->new(keep_alive=>1);
	$ua->credentials('www.company.com:80', '', "MyDomain\\MyUserCode", 'MyPassword');

	$request = GET $url;
	print "--Performing request now...-----------\n";
	$response = $ua->request($request);
	print "--Done with request-------------------\n";

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

DESCRIPTION
       "LWP::Authen::Ntlm" allows LWP to authenticate against servers that are using the NTLM
       authentication scheme popularized by Microsoft.	This type of authentication is common on
       intranets of Microsoft-centric organizations.

       The module takes advantage of the Authen::NTLM module by Mark Bush.  Since there is also
       another Authen::NTLM module available from CPAN by Yee Man Chan with an entirely different
       interface, it is necessary to ensure that you have the correct NTLM module.

       In addition, there have been problems with incompatibilities between different versions of
       Mime::Base64, which Bush's Authen::NTLM makes use of.  Therefore, it is necessary to
       ensure that your Mime::Base64 module supports exporting of the encode_base64 and
       decode_base64 functions.

USAGE
       The module is used indirectly through LWP, rather than including it directly in your code.
       The LWP system will invoke the NTLM authentication when it encounters the authentication
       scheme while attempting to retrieve a URL from a server.  In order for the NTLM
       authentication to work, you must have a few things set up in your code prior to attempting
       to retrieve the URL:

       o   Enable persistent HTTP connections

	   To do this, pass the "keep_alive=>1" option to the LWP::UserAgent when creating it,
	   like this:

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

       o   Set the credentials on the UserAgent object

	   The credentials must be set like this:

	      $ua->credentials('www.company.com:80', '', "MyDomain\\MyUserCode", 'MyPassword');

	   Note that you cannot use the HTTP::Request object's authorization_basic() method to
	   set the credentials.  Note, too, that the 'www.company.com:80' portion only sets
	   credentials on the specified port AND it is case-sensitive (this is due to the way LWP
	   is coded, and has nothing to do with LWP::Authen::Ntlm)

AVAILABILITY
       General queries regarding LWP should be made to the LWP Mailing List.
