How to get the Session ID from a Zend_Auth session?

Using the default Zend_Auth session storage (PHP Sessions), it creates a session ID and puts it in a cookie. If I want to get at the authenticated user's username (identity), the Zend_Auth::getInstance()->getIdentity() method gets that. However, I want to get at the user's session ID. I can get at it just by looking at $_COOKIE, or using session_id() but that seems hackish, and if I ever moved away from PHP Session storage might it break? So what's the best way to get the current session ID of the Zend_Auth session?

I don't think you're going to find a nice way to do this. If such a method existed it would be defined in Zend_Auth_Storage_Interface, but non-session types of storage don't necessarily have a session ID equivalent so the auth storage classes don't have any abstraction for this. The closest you'll get is probably:

Zend_Session::getId()

but this just calls PHP's session_id(), since Zend_Session is dependent on the in-built PHP session functionality.
