NAME

6       LWP::Authen::Negotiate - GSSAPI based Authentication Plugin for LWP
7

SYNOPSIS

9          #! /usr/bin/perl -w
10
11          use strict;
12          require LWP::UserAgent;
13
14          # uncomment if you want see what is going wrong messages
15          #
16          #use LWP::Debug qw(+);
17
18          my $ua = LWP::UserAgent->new;
19          my $response = $ua->get('http://testwurst.grolmsnet.lan:8090/geheim/');
20          if ($response->is_success) {
21             print $response->content;  # or whatever
22          }
23          else {
24              die $response->status_line;
25          }
26
27       just install LWP::Authen::Negotiate, LWP uses it as authentication
28       plugin.  Use your LWP::UserAgent Scripts as usual.  Authentication is
29       done transparent based on your GSSAPI installation (MIT Kerberos or
30       Heimdal)
31
32       WWW-Negotiate Webservers are IIS or Apache with mod_auth_kerb for
33       example.

46
47          use LWP::Debug qw(+);
48
49       to yor LWP using Scripts.
50
51       (e.g. too see what is going wrong with GSSAPI...)
52
53       the output will look like this:
54
55          LWP::UserAgent::new: ()
56          LWP::UserAgent::request: ()
57          LWP::UserAgent::send_request: GET http://testwurst.grolmsnet.lan:8090/geheim/
58          LWP::UserAgent::_need_proxy: Not proxied
59          LWP::Protocol::http::request: ()
60          LWP::Protocol::collect: read 478 bytes
61          LWP::UserAgent::request: Simple response: Unauthorized
62          LWP::Authen::Negotiate::authenticate: authenticate() called
63          LWP::Authen::Negotiate::authenticate: target hostname testwurst.grolmsnet.lan
64          LWP::Authen::Negotiate::authenticate: GSSAPI servicename     HTTP/moerbsen.grolmsnet.lan@GROLMSNET.LAN
65          LWP::Authen::Negotiate::authenticate:  Miscellaneous failure (see text)
66          LWP::Authen::Negotiate::authenticate: open(/tmp/krb5cc_1000): file not found
67
68       In this case the credentials cache was empty.  Run kinit first ;-)

BUGS

93       As default Kerberos 5 is selected as GSSAPI mechanism.  a later veriosn
94       will make that configureable.
