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
       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 authentica-
       tion 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 attempt-
       ing 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 = new LWP::UserAgent(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 authoriza-
           tion_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)

       If you run into trouble and need help troubleshooting your problems,
       try enabling LWP debugging by putting this line at the top of your
       code:

           use LWP::Debug qw(+);

       You should get copious debugging output, including messages from
       LWP::Authen::Ntlm itself.
