Serializing objects and storing them is sessions

I'm having a problem unserializing objects that are passed from page to page with sessions. Registered globals is disabled so I am using the $_SESSION array to store session variable and am not using session_register(). Here's what I'm doing. On first page: $auth = new Class(); session_start(); $_SESSION['auth'] = serialize($auth); Second page: session_start(); var_dump($_SESSION); $auth = unserialize($_SESSION['auth']); var_dump($auth); When I var_dump() $_SESSION it appears to be a string representation of the object. However, when I try to unserialize() it and store it in $auth the value is bool(false) and not an object. Can anyone tell me what I am doing wrong?
