I have a question about user authentication in my WordPress Multisite site.
My site is http://www.drezzy.it that has its own user db with a login and logout system. This is a non-WP website. When you login, it gives a cookie which include the email and the password of the user.
I created a WordPress Multisite website inside this one, http://www.drezzy.it/community/speciale/ that can have access to the cookie.
My questions are:
How can I allow WordPress to log in users by using the main site's cookie, so that they don't have to register or log in again? A sort of bridge between the main site and WP that would enable to log in only once for all.
How can I create a new user in WP for each user logged in the main website?
P.S. I'm sorry for my English, if you have some troubles with understand it, ask me, I will explain better! :D
