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


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         => '',
         globalStorage  => 'Apache::Session::MySQL',
         globalStorageOptions => {
           DataSource   => 'dbi:mysql:database',
           UserName     => 'db_user',
           Password     => 'db_password',
           TableName    => 'sessions',
         ldapServer     => '',
         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',
         # SSLLDAPField: field to use in ldap filter to search SSLVar
         #               default: mail
         SSLLDAPField   => 'cn',
         # SSLRequire: if set to 1, login/password are disabled
         #             default: 1
         SSLRequire     => 1,

  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=utf8'); # 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=utf8'); # 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


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

The parameter SSLRequire can be used to authenticate users by SSL or ldap bind. If SSL is used, authenticationLevel is set to 5. You can use this parameter in 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 Lemonldap::NG::Portal::Simple for usage and other methods.
