I am using a script I got from http://phpsense.com/php/php-login-script.html in order to allow people to login but prevent multiple logins with the same username. Everything appears to work fine however multiple people can still login simultaneously. I have verified sessions are being stored with the correct info and it appears cookies are generated as well so why can people login with the same username from different machines simultaneously?
