Write a custom plugin

You can now write a custom portal plugin that will hook in the authentication process:

• beforeAuth: method called before authentication process
• betweenAuthAndData: method called after authentication and before setting “sessionInfo” provisionning
• afterData: method called after “sessionInfo” provisionning
• endAuth: method called when session is validated (after cookie build)
• authCancel: method called when user click on “cancel” during auth process
• forAuthUser: method called for already authenticated users
• beforeLogout: method called before logout

The plugin can also define new routes and call actions on them.

See also Lemonldap::NG::Portal::Main::Plugin man page.

Create for example the MyPlugin module:

vi /usr/share/perl5/Lemonldap/NG/Portal/MyPlugin.pm

package Lemonldap::NG::Portal::MyPlugin;
 
use Mouse;
use Lemonldap::NG::Portal::Main::Constants;
extends 'Lemonldap::NG::Portal::Main::Plugin';
 
use constant beforeAuth => 'verifyIP';
 
sub init {
          my ($self) = @_;
          $self->addUnauthRoute( mypath => 'hello', [ 'GET', 'PUT' ] );
          $self->addAuthRoute( mypath => 'welcome', [ 'GET', 'PUT' ] );
          return 1;
}
sub verifyIP {
          my ($self, $req) = @_;
          return PE_ERROR if($req->address !~ /^10/);
          return PE_OK;
}
sub hello {
          my ($self, $req) = @_;          
          ...
          return $self->p->sendJSONresponse($req, { hello => 1 });
}
sub welcome {
          my ($self, $req) = @_;          
 
          my $userid = $req->user;
          $self->p->logger->debug("Call welcome for $userid");
 
          ...
          return $self->p->sendHtml($req, 'template', params => { WELCOME => 1 });
}
1;

Declare the plugin in lemonldap-ng.ini:

vi /etc/lemonldap-ng/lemonldap-ng.ini

[portal]
customPlugins = Lemonldap::NG::Portal::MyPlugin
;customPlugins = Lemonldap::NG::Portal::MyPlugin1, Lemonldap::NG::Portal::MyPlugin2, ...
