Restrict customer from being able to login to other store

[yonghan79]

Hi core devs,

how do we restrict customer from being able to login to other store that was set by using multistore?

e.g. we have a VIP and Wholesale store. Wholesale customer should not be able to login to VIP store.

AbanteCart v1.3.4 and v1.4.0.

Hello.
It's possible to create a restriction, but what should happen if the customer tries to register at other stores with the same email? What about customer groups?
