I'm looking for a solution to share users across several websites, I mean when you're registered on one site you're registered on all others.
define('CUSTOM_USER_TABLE', 'wp_users'); define('CUSTOM_USER_META_TABLE', 'wp_usermeta');
So I got the login/password informations shared across websites which is good.
However I got a problem with the user role as it is prefixed with db_prefix.
How can I automatically assign a default user role (let's say "contributor" if the user successfully connect and as no current user role?
