so i am doing sso on a store. it works great, nice feature. i want to be able to allow users to sign up and check out without authorization still, however. is this even possible with sso? i want an authorized user to be logged in automatically, but for new users, i want them to go through the process of account creation in foxy carts sexy ajax'd method of check out. it seems like there is no way to do this. am i doing it wrong? thanks!
