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 = new LWP::UserAgent(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 organiza-
       tions.

       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:

       ?   Enable persistent HTTP connections

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

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

       ?   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)

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