Tengo una aplicación de terceros (responsivefilemanager plugin paraTinyMCE) que no puedo reescribirlo usandoSymfony2.
Necesito protegerlo contra usuarios no autorizados.
¿Es posible acceder?Symfony2¿Las variables de sesión (usuario, roles, etc.) de la aplicación externa?¿Cómo?
Traté de hacersession_start() y leer$_SESSION Variable, pero está vacío!
