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 = LWP::UserAgent->new(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"}

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"
41 functions.
42
44 The module is used indirectly through LWP, rather than including it
45 directly in your code. The LWP system will invoke the NTLM
46 authentication when it encounters the authentication scheme while
47 attempting to retrieve a URL from a server. In order for the NTLM
48 authentication to work, you must have a few things set up in your code
49 prior to attempting to retrieve the URL:
50
51 • Enable persistent HTTP connections
52
53 To do this, pass the "keep_alive=>1" option to the LWP::UserAgent
54 when creating it, like this:
55
56 my $ua = LWP::UserAgent->new(keep_alive=>1);
57
58 • Set the credentials on the UserAgent object
59
60 The credentials must be set like this:
61
62 $ua->credentials('www.company.com:80', '', "MyDomain\\MyUserCode", 'MyPassword');
63
64 Note that you cannot use the HTTP::Request object's
65 "authorization_basic()" method to set the credentials. Note, too,
66 that the 'www.company.com:80' portion only sets credentials on the
67 specified port AND it is case-sensitive (this is due to the way LWP
68 is coded, and has nothing to do with LWP::Authen::Ntlm)
69
71 General queries regarding LWP should be made to the LWP Mailing List.
