PayPal Fails if a Password Field is Provided

[gordonbanderson]

hi,

I spent some time banging my head before I got to the bottom of this. It turns out that is a password field is provided, as below, then the initial authentication step of purchase does not work and payment is immediately cancelled.

Payload that works:

Array

                        )

                )

        )

)

This relates to the initiate($data) method on this page, https://github.com/silverstripe/silverstripe-omnipay/blob/master/docs/en/GettingStarted.md

Documentation should probably be updated to save others pain :)
