NAME

    Lemonldap::Handlers::Generic  - Perl extension for Lemonldap sso system

    Lemonldap::Handlers::Generic4a2 - Handler for Apache2 Lemonldap SSO
    system

SYNOPSIS

In httpd.conf

  .....
  perltranshandler Lemonldap::Handlers::Generic4a2
  .....

DESCRIPTION

 Generic4a2 is the central piece of  websso framework .
 This module provides several methods but the principal goal of this is the handler function .
 It can be combined with mod_proxy or mod_rewrite and all other apache's  modules .
 It provides also an built-in  http proxy with LWP .
 see http://lemonldap.sf.net for more infos .

Parameters (see also doc folder)

 A minimal configuration  must provide  infos about :
config
 PerlSetVar ConfigFile /usr/local/apache/conf/config_demo1.xml 

 The filename of the mean XML Config   :It's REQUIRED
domain
 PerlSetVar Domain demo.net
 
 It fixes the value of domain for the  application protected by  this handler (see below)
xml section in config
 Perlsetvar HandlerID <xml section>

 It fixes the value of XML section in config

Example (a KISS example, see also eg folder)

In httpd.conf

 <virtualHost 127.0.0.1:80>
 servername authen.demo.net
 PerlModule Apache2::compat
 PerlModule Bundle::Apache2
 PerlModule Lemonldap::Handlers::Generic4a2 
 perltranshandler Lemonldap::Handlers::Generic4a2
 PerlSetVar Domain demo.net
 PerlSetVar Configfile /usr/local/apache/conf/application_new.xml
 PerlSetVar HandlerID myintranet
 proxypass /intranet http://lemonldap.sourceforge.net
 proxypassreverse /intranet  http://lemonldap.sourceforge.net
 documentroot /usr/local/apache/htdocs
 </virtualhost>


 In /usr/local/apache/conf/application_new.xml
  <lemonconfig>
        <domain    id="demo.net"
                   Cookie="lemondemo"
                            >
                 <handler 
                         id="myintranet" 
                          DisableAccessControl= "1"
                        />  
        </domain>
  </lemonconfig>

   
 Now you can put http://authen.demo.net/intranet/ in your browser and you will see lemonldap's  site
 AND now you can control who and where goes on your site .
  
 You can pass parameters from httpd.conf with perlsetvar  facilities  or put them in xml file

Functions

handler
 It's the mean  function which does all jobs . If the enebledproxy parameter is set to 1  ,this function
 will push proxy_handler function reference on  the handler's stack . If not it returns DECLINED (mod_proxy will be actived)
proxy_handler
 It's the built-in proxy (LWP)  web embedded  in lemonldap framework . It is  actived by  enabledproxy parameter .
 Some parameters are about this proxy and its behaviour
_lemonldap_debug
  append this keyword at the end of url and you will can see all headers send to host.
  Available  ONLY with built-in proxy

Features

Generic4a2 is build arround perl's modules .

Those modules are :

Utilities :
  collection of functions
Core :
  It provides basics services like the cache service, forge header service or authorization service.
  
 Core.pm  can use YOUR own services for all this cycle . It's plugger . Lemonldap framework is available 
 with somes services but you can with Core.pm propose your own schemas.
 News parameters  were added in XML DTD in order to describe the sequence.
MatrixPolicy :
 manage authorization process , based on the hash of session (like preceding version)
Memsession :
 manage the backend of session (cache level 3 and 4 )
AuthorizationHeader :
 manage the construction of header
RewriteHTML :
 Rewrite on fly html source in order to ajust somes tags like BASE , href or src
 Available  ONLY with built-in proxy

More features

Authentification
 Keep in mind  that the handler doesn't know HOW authenticate anybody but only knows WHERE authenticate . 
 The parameter 'portal' tells it where to send the authentification request.
Caches
 Thre are three levels of cache in lemonldap . 

 *First cache (level 1) is a very KISS  , it's a memory structure in the program .
 *Next  cache (level 2) is realised by using berkeleyDB hash
 *Last cache (level 3) is realised by using memcached (see Apache::Session::Memorycached on CPAN)
