I have created multiple sites, that has user identification like here:
How to get unique users across multiple Django sites powered by the "sites" framework?
But, how to make user unique for every website where he registered ?
For example:
Arti at domain.com
Arti at domain2.com
It's two different users, but create another Arti at domain.com
impossible, and i'll get an error: "User is already exist".
