php session does not carry across subdomains

Last Modified: 2013-11-10
I have an issue where I need a script to read the same session no matter what subdomain the person is using. Anotherwords, I need the person to stay logged in even if they jump subdomains. I tried setting the below at the top of every page but it still doesn't work. When I try to read the session on a new subdomain it just creates a brand new one.
ini_set("session.cookie_domain", ".domain.com");
