Custom Authentication Provider symfony2
So I'm using this tutorial on [How to create custom auth][1] but I'm getting an exception of:

    [Symfony\Component\Config\Definition\Exception\InvalidConfigurationException]  
    Unrecognized options "factories" under "security"                              

Anyone knows what the issue is? Has something changed recently in the framework and hence making this tutorial out of date? If yes how can I go about finding out about it?

Thanks,
Reza
