NAME
       AuthCAS - Client library for CAS 2.0 authentication server

VERSION
       Version 1.5

DESCRIPTION
       AuthCAS aims at providing a Perl API to Yale's Central Authentication
       System (CAS). Only a basic Perl library is provided with CAS whereas
       AuthCAS is a full object-oriented library.  =head1 PREREQUISITES

       This script requires IO::Socket::SSL and LWP::UserAgent

       any

       Network

SYNOPSIS
	 A simple example with a direct CAS authentication

	 use AuthCAS;
	 my $cas = new AuthCAS(casUrl => 'https://cas.myserver,
			   CAFile => '/etc/httpd/conf/ssl.crt/ca-bundle.crt',
			   );

	 my $login_url = $cas->getServerLoginURL('http://myserver/app.cgi');

	 ## The user should be redirected to the $login_url
	 ## When coming back from the CAS server a ticket is provided in the QUERY_STRING

	 ## $ST should contain the receaved Service Ticket
	 my $user = $cas->validateST('http://myserver/app.cgi', $ST);

	 printf "User authenticated as %s\n", $user;

	 In the following example a proxy is requesting a Proxy Ticket for the target application

	 $cas->proxyMode(pgtFile => '/tmp/pgt.txt',
			 pgtCallbackUrl => 'https://myserver/proxy.cgi?callback=1
			 );

	 ## Same as before but the URL is the proxy URL
	 my $login_url = $cas->getServerLoginURL('http://myserver/proxy.cgi');

	 ## Like in the previous example we should receave a $ST

	 my $user = $cas->validateST('http://myserver/proxy.cgi', $ST);

	 ## Process errors
	 printf STDERR "Error: %s\n", &AuthCAS::get_errors() unless (defined $user);

	 ## Now we request a Proxy Ticket for the target application
	 my $PT = $cas->retrievePT('http://myserver/app.cgi');

	 ## This piece of code is executed by the target application
	 ## It received a Proxy Ticket from the proxy
	 my ($user, @proxies) = $cas->validatePT('http://myserver/app.cgi', $PT);

	 printf "User authenticated as %s via %s proxies\n", $user, join(',',@proxies);

DESCRIPTION
       CAS is Yale University's web authentication system, heavily inspired by
       Kerberos.  Release 2.0 of CAS provides "proxied credential" feature
       that allows authentication tickets to be carried by intermediate
       applications (Portals for instance), they are called proxy.

       This AuthCAS Perl module provides required subroutines to validate and
       retrieve CAS tickets.
