Christophe is right: define a new service and give him the DBAL service as a dependency.
Then you can define this service as a security provider like this: providers: my_provider: id: my_service_id where "my_service_id" is the id of the service you defined in the DIC. Your service has to implement http://api.symfony-reloaded.org/PR4/Symfony/Component/Security/User/UserProviderInterface.html But as Christophe said, you should use FOS\UserBundle ( https://github.com/FriendsOfSymfony/UserBundle ). -- If you want to report a vulnerability issue on symfony, please send it to security at symfony-project.com You received this message because you are subscribed to the Google Groups "symfony users" group.
