No login with multiple buyers?

[pandpdeveloper]

I've recently set up a customer account with multiple buyers within it- all with seperate login details (username/password etc).

Why can I not log in as any of these buyers, yet I can log in to a main customer level account

By the way, the error message I get is:

No such user (or invalid password)

Did you upload/refresh your site after adding buyers?
