Hi,

I'm "kicking the tires" at the moment and was wondering if it's possible to pre-fill fields on a registration form? Specifically with data from an identity provider.

A scenario could be to use Facebook as an identity provider. From Facebook you can request the users birthday which could be required data in an application for age checks. So, birthday would be a required field in a form. We may get the birthday from the identity provider. Ok, bad example. Birthday is a required field in Facebook so it will always be there so let's replace FB with another identity provider where birthday is optional.

So, the user has completed the login step with the identity provider and is dropped back into a registration form where birthday is a mandatory field. It would be nice if that mandatory field was pre-filled with the birthday from the identity provider if one was available.
