**IMPORTANT:** **Customer Registration Fails when using generic Magento 5-step checkout.**

**This issue is only presented when we ENABLE form key authentication.** Version used: 1.7.0.2, but looks like someone has posted that same issue occurs on 1.9.3 version too.

When Go to checkout, we are presented with 2 options: CHECKOUT AS A GUEST OR REGISTER
Once click "Register", and fill-out the form along with password, you proceed throguh all steps and complete the order. Order gets placed, BUT customer never gets registered in magento. It looks like Guest order form the backend.


When I went back and **Disabled** form key authentication, and tried placing order while registering as a customer, it got placed without any problems and the customer got registered in the backend.
