NAME

Lemonldap::NG::Handler::Simple - Perl base extension for building Lemonldap::NG compatible handler.

SYNOPSIS

Create your own package:

  package My::Package;
  use Lemonldap::NG::Handler::Simple;

  our @ISA = qw(Lemonldap::NG::Handler::Simple);

  __PACKAGE__->init ({
         locationRules        => {
               default          => '$ou =~ /brh/'
         },
         globalStorage        => 'Apache::Session::MySQL',
         globalStorageOptions => {
               DataSource       => 'dbi:mysql:database=dbname;host=127.0.0.1',
               UserName         => 'db_user',
               Password         => 'db_password',
               TableName        => 'sessions',
               LockDataSource   => 'dbi:mysql:database=dbname;host=127.0.0.1',
               LockUserName     => 'db_user',
               LockPassword     => 'db_password',
           },
         localStorage         => 'Cache::DBFile',
         localStorageOptions  => {},
         portal               => 'https://portal/',
       });

More complete example

  package My::Package;

  __PACKAGE__->init ( { locationRules => {
             '^/pj/.*$'       => '$qualif="opj"',
             '^/rh/.*$'       => '$ou=~/brh/',
             '^/rh_or_opj.*$' => '$qualif="opj" or $ou=~/brh/',
             default => 'accept', # means that all authenticated users are greanted
           },
           globalStorage        => 'Apache::Session::MySQL',
           globalStorageOptions => {
               DataSource       => 'dbi:mysql:database=dbname;host=127.0.0.1',
               UserName         => 'db_user',
               Password         => 'db_password',
               TableName        => 'sessions',
               LockDataSource   => 'dbi:mysql:database=dbname;host=127.0.0.1',
               LockUserName     => 'db_user',
               LockPassword     => 'db_password',
           },
           localStorage         => 'Cache::DBFile',
           localStorageOptions  => {},
           cookieName           => 'lemon',

               'Auth-User'      => '$uid',
               'Unit'           => '$ou',
           https                => 1,
         }

DESCRIPTION

Lemonldap::NG::Handler::Simple is designed to be overloaded. See Lemonldap::NG::Handler for more.

INITIALISATION PARAMETERS

This section presents the init method parameters.

locationRules (required)

Reference to a hash that contains "url-regexp => perl-expression" entries to manage authorizations.

• "url-regexp" can be a perl regexp or the keyword 'default' which corresponds to the default police (accept by default).

• "perl-expression" can be a perl condition or the keyword "accept" or the keyword "deny". All the variables announced by $<name of the variable> are replaced by the values resulting from the global session store.

globalStorage & globalStorageOptions (required)

Name and parameters of the Apache::Session::* module used by the portal to store user's datas. See Lemonldap::NG::Portal(3) for more explanations.

localStorage & localStorageOptions

Name and parameters of the optional but recommended Cache::* module used to share user's datas between Apache processes. There is no need to set expires options since Lemonldap::NG::Handler::Simple call the Cache::*::purge method itself.

cookieName (default: lemon)

Name of the cookie used by the Lemonldap::NG infrastructure.

portal (required)

Url of the portal used to authenticate users.

whatToTrace (default: uid)

Stored user variable to use in Apache logs.

exportedHeaders

Reference to a hash that contains "Name => value" entries. Those headers are calculated for each user by replacing the variables announced by "$" by their values resulting from the global session store.

https (default: 1)

Indicates if the protected server is protected by SSL. It is used to build redirections, so you have to set it to avoid bad redirections after authentication.

port (default: undef)

If port is not well defined in redirection, you can fix listen port here.

EXPORT

None by default. You can import the following tags for inheritance:

• :localStorage : variables used to manage local storage

• :globalStorage : variables used to manage global storage

• :locationRules : variables used to manage area protection

• :import : import function inherited from Exporter and related variables

• :headers : functions and variables used to manage custom HTTP headers exported to the applications

• apache : functions and variables used to dialog with mod_perl. This is done to be compatible both with Apache 1 and 2.
