We have a client that is having a problem with users sharing the same login. The problem is that these users are in an office environment and they share the same outgoing IP address. So the multiple IP addresses in X minutes is not working. Is there a way to detect (maybe using session variables?) when the same user id is already logged in and then give the option to either cancel the login or logout the other user? Was thinking that deleting the existing session might work. Any other suggestions would be appreciated.
