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:

    *   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);

    *   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.
