LWP::Authen::Negotiate(3pm) User Contributed Perl Documentation LWP::Authen::Negotiate(3pm) NAME
LWP::Authen::Negotiate - GSSAPI based Authentication Plugin for LWP SYNOPSIS
#! /usr/bin/perl -w use strict; require LWP::UserAgent; # uncomment if you want see what is going wrong messages # #use LWP::Debug qw(+); my $ua = LWP::UserAgent->new; my $response = $ua->get('http://testwurst.grolmsnet.lan:8090/geheim/'); if ($response->is_success) { print $response->content; # or whatever } else { die $response->status_line; } just install LWP::Authen::Negotiate, LWP uses it as authentication plugin. Use your LWP::UserAgent Scripts as usual. Authentication is done transparent based on your GSSAPI installation (MIT Kerberos or Heimdal) WWW-Negotiate Webservers are IIS or Apache with mod_auth_kerb for example. DESCRIPTION
To see what ist going on add use LWP::Debug qw(+); to yor LWP using Scripts. (e.g. too see what is going wrong with GSSAPI...) DEBUGGING
To see what ist going on (and going wrong) add use LWP::Debug qw(+); to yor LWP using Scripts. (e.g. too see what is going wrong with GSSAPI...) the output will look like this: LWP::UserAgent::new: () LWP::UserAgent::request: () LWP::UserAgent::send_request: GET http://testwurst.grolmsnet.lan:8090/geheim/ LWP::UserAgent::_need_proxy: Not proxied LWP::Protocol::http::request: () LWP::Protocol::collect: read 478 bytes LWP::UserAgent::request: Simple response: Unauthorized LWP::Authen::Negotiate::authenticate: authenticate() called LWP::Authen::Negotiate::authenticate: target hostname testwurst.grolmsnet.lan LWP::Authen::Negotiate::authenticate: GSSAPI servicename HTTP/moerbsen.grolmsnet.lan@GROLMSNET.LAN LWP::Authen::Negotiate::authenticate: Miscellaneous failure (see text) LWP::Authen::Negotiate::authenticate: open(/tmp/krb5cc_1000): file not found In this case the credentials cache was empty. Run kinit first ;-) ENVIRONMENT
