Great opportunity for DoS attacks. ;-)
After being asked off list:
Sorry, maybe I got the original poster wrong.
My first thought was if someone manages to grab the session ID he/she can
logout the valid user immediately by trying to access the web application
with this session ID.
But after rethinking maybe the original poster thought about a second login
with a *valid* authentication. This would not be vulnerable to DoS attack.
Well, still I'd assume it's bad advice to close all sessions. A better
approach would be to refuse the second login.
