I'm using **FOSUserBundle** for **Symfony2**, and I need to be able to register a user **without validating if the email is Unique**, I just need a valid email so **many users can have the same email** ( I know this is weird, but I need it).

I have an entity "User" in a bundle that **extends FOSUserBundle**, is it possible to **overwrite the column definition** of emailCanonical to eliminate the unique parameter and remove the validation from the FormType?

I'm using Annotation for mapping my Entities and YML for validation of my forms.
