I am using BM 3.7sp3 on netware 6.5 sp3 server. I am having an issue with out Mac users. When they attempt to access internet in the morning they are prompted to log in as they should be. However, they can leave the connection open and come back hours later and are still able to connect. Our settings specify that they should log back in after 15 minutes of inactivity.

We are running transparent proxy. This is working fine for PCs, only an issue for Macs. Anybody have any ideas?
