NAME

6       LWP::Authen::Ntlm - Library for enabling NTLM authentication (Micro‐
7       soft) in LWP
8

SYNOPSIS

10        use LWP::UserAgent;
11        use HTTP::Request::Common;
12        my $url = 'http://www.company.com/protected_page.html';
13
14        # Set up the ntlm client and then the base64 encoded ntlm handshake message
15        my $ua = new LWP::UserAgent(keep_alive=>1);
16        $ua->credentials('www.company.com:80', '', "MyDomain\\MyUserCode", 'MyPassword');
17
18        $request = GET $url;
19        print "--Performing request now...-----------\n";
20        $response = $ua->request($request);
21        print "--Done with request-------------------\n";
22
23        if ($response->is_success) {print "It worked!->" . $response->code . "\n"}
24        else {print "It didn't work!->" . $response->code . "\n"}

DESCRIPTION

27       "LWP::Authen::Ntlm" allows LWP to authenticate against servers that are
28       using the NTLM authentication scheme popularized by Microsoft.  This
29       type of authentication is common on intranets of Microsoft-centric
30       organizations.
31
32       The module takes advantage of the Authen::NTLM module by Mark Bush.
33       Since there is also another Authen::NTLM module available from CPAN by
34       Yee Man Chan with an entirely different interface, it is necessary to
35       ensure that you have the correct NTLM module.
36
37       In addition, there have been problems with incompatibilities between
38       different versions of Mime::Base64, which Bush's Authen::NTLM makes use
39       of.  Therefore, it is necessary to ensure that your Mime::Base64 module
40       supports exporting of the encode_base64 and decode_base64 functions.
41

USAGE

43       The module is used indirectly through LWP, rather than including it
44       directly in your code.  The LWP system will invoke the NTLM authentica‐
45       tion when it encounters the authentication scheme while attempting to
46       retrieve a URL from a server.  In order for the NTLM authentication to
47       work, you must have a few things set up in your code prior to attempt‐
48       ing to retrieve the URL:
49
50       ·   Enable persistent HTTP connections
51
52           To do this, pass the "keep_alive=>1" option to the LWP::UserAgent
53           when creating it, like this:
54
55               my $ua = new LWP::UserAgent(keep_alive=>1);
56
57       ·   Set the credentials on the UserAgent object
58
59           The credentials must be set like this:
60
61              $ua->credentials('www.company.com:80', '', "MyDomain\\MyUserCode", 'MyPassword');
62
63           Note that you cannot use the HTTP::Request object's authoriza‐
64           tion_basic() method to set the credentials.  Note, too, that the
65           'www.company.com:80' portion only sets credentials on the specified
66           port AND it is case-sensitive (this is due to the way LWP is coded,
67           and has nothing to do with LWP::Authen::Ntlm)
68
69       If you run into trouble and need help troubleshooting your problems,
70       try enabling LWP debugging by putting this line at the top of your
71       code:
72
73           use LWP::Debug qw(+);
74
75       You should get copious debugging output, including messages from
76       LWP::Authen::Ntlm itself.
