Lemonldap::NG::Portal::AuthSSL - Perl extension for building Lemonldap::NG
compatible portals with SSL authentication.

=head1 SYNOPSIS

With Lemonldap::NG::Portal::SharedConf, set authentication field to "SSL" in
configuration database.

With Lemonldap::NG::Portal::Simple:

  use Lemonldap::NG::Portal::Simple;
  my $portal = new Lemonldap::NG::Portal::Simple(
         domain         => 'example.com',
         globalStorage  => 'Apache::Session::MySQL',
         globalStorageOptions => {
           DataSource   => 'dbi:mysql:database',
           UserName     => 'db_user',
           Password     => 'db_password',
           TableName    => 'sessions',
         },
         ldapServer     => 'ldap.domaine.com',
         securedCookie  => 1,
         authentication => 'SSL',
         
         # SSLVar: field to search in client certificate
         #         default: SSL_CLIENT_S_DN_Email the mail address
         SSLVar         => 'SSL_CLIENT_S_DN_CN',
    );

  if($portal->process()) {
    # Write here the menu with CGI methods. This page is displayed ONLY IF
    # the user was not redirected here.
    print $portal->header('text/html; charset=utf-8'); # DON'T FORGET THIS (see CGI(3))
    print "...";

    # or redirect the user to the menu
    print $portal->redirect( -uri => 'https://portal/menu');
  }
  else {
    # If the user enters here, IT MEANS THAT YOUR SSL PARAMETERS ARE BAD
    print $portal->header('text/html; charset=utf-8'); # DON'T FORGET THIS (see CGI(3))
    print "<html><body><h1>Unable to work</h1>";
    print "This server isn't well configured. Contact your administrator.";
    print "</body></html>";
  }

Modify your httpd.conf:

  <Location /My/File>
    SSLVerifyClient optional # or 'require' if login/password are disabled
    SSLOptions +StdEnvVars
  </Location>

=head1 DESCRIPTION

This library just overload few methods of Lemonldap::NG::Portal::Simple to use
Apache SSLv3 mechanism: we've just to verify that
C<$ENV{SSL_CLIENT_S_DN_Email}> exists. So remenber to export SSL variables
to CGI.

If SSL is used, authenticationLevel is set to 5. You can use this parameter in
L<Lemonldap::NG::Handler> rules to force users to use certificates in some
applications:

  virtualHost1 => {
    'default' => '$authenticationLevel > 5 and $uid = "jeff"',
  },

Note that you can use Apache SSL environment variables in "exported variables".

See L<Lemonldap::NG::Portal::Simple> for usage and other methods.
