I notice WPA_GUI has saved my WiFi password to
/etc/wpa_supplicant/wpa_supplicant.conf. The unit I'm trying to set up is a shared use system on enterprise WiFi that logs on with a user's account, so leaking the password between users is a very bad thing. There's no option in WPA_GUI to not save the password.
How can I set the system up to force each user to give their username/password to connect, and not have them stored? Note I would prefer to avoid using actual corresponding user accounts on the system.
