I am using PHPAnthology's sessions and logging them in a Mysql Database... Im trying to keep the user logged in across subdomains ie... user logs in on subdomain1.mydomain.com and then clicks on a link to subdomain2.mydomain.com. How can I keep the user logged it. I have the database working correctly. Currently it logs a session for each subdomain and the user must log in twice.

Is there a way to keep them logged in?
