check if sessions are inactive

Ok, I've developed a system that allows N number of users to log-in to the
site under the same username/password combo. If a user account has a maximum
of 5 possible simultaneous user log-ins, the user stack will be full unless
those users logout (which will reduce the stack by one), or their session
expires. The problem being that I do not know how to check if a session is
active, other than checking the current user session (not all session's
currently associated with an account). I am storing all sessions associated
with an account. Any ideas? Thanks in advance
