NAME

       Lemonldap::NG::Handler::SharedConf - Perl extension to use dynamic configuration provide
       by Lemonldap::NG::Manager.

SYNOPSIS

         package My::Package;
         use Lemonldap::NG::Handler::SharedConf;
         @ISA = qw(Lemonldap::NG::Handler::SharedConf);
         __PACKAGE__->init ( {
           localStorage        => "Cache::FileCache",
           localStorageOptions => {
               'namespace' => 'lemonldap-ng',
               'default_expires_in' => 600,
             },
           configStorage       => {
              type                => "DBI"
              dbiChain            => "DBI:mysql:database=$database;host=$hostname;port=$port",
              dbiUser             => "lemonldap",
              dbiPassword         => "password",
             },
         } );

       Call your package in /apache-dir/conf/httpd.conf :

         PerlRequire MyFile
         # TOTAL PROTECTION
         PerlHeaderParserHandler My::Package
         # OR SELECTED AREA
         <Location /protected-area>
           PerlHeaderParserHandler My::Package
         </Location>

       The configuration is loaded only at Apache start. Create an URI to force configuration
       reload, so you don't need to restart Apache at each change :

         # /apache-dir/conf/httpd.conf
         <Location /location/that/I/ve/choosed>
           Order deny,allow
           Deny from all
           Allow from my.manager.com
           PerlHeaderParserHandler My::Package->refresh
         </Location>

DESCRIPTION

       This library inherit from Lemonldap::NG::Handler::Simple to build a complete SSO Handler
       System: a central database contains the policy of your domain. People that want to access
       to a protected applications are redirected to the portal that run
       Lemonldap::NG::Portal::SharedConf. After reading configuration from the database and
       authenticating the user, it stores a key word for each application the user is granted to
       access to.  Then the user is redirected to the application he wanted to access and the
       Apache handler build with Lemonldap::NG::Handler::SharedConf::DBI has just to verify that
       the keyword corresponding to the protected area is stored in the database.

   OVERLOADED SUBROUTINES
       init

       Like Lemonldap::NG::Handler::Simple::init() but read only localStorage related options.
       You may change default time between two configuration checks with the "reloadTime"
       parameter (default 600s).

OPERATION

       Each new Apache child checks if there's a configuration stored in the local store. If not,
       it calls getConf to get one and store it in the local store by calling setconf.

       Every 600 seconds, each Apache child checks if the local stored configuration has changed
       and reload it if it has.

       When refresh subroutine is called (by http for example: see synopsis), getConf is called
       to get the new configuration and setconf is called to store it in the local store.
