force captive portal reauthentication after log off on fortios 5.4

Hello guys, 
I'm trying to re-authenticate users connected to a Captive Portal Interface (wired) after a log off (whatever reason, ex: switch port disconnection). When one of my desktop are disconnected from the switch port and is connected it back again. The PC never re-authenticate. It just allow access. 
How could I modified this default behavior.
 
 
Thanks guys,

    I'm not sure though if your requirement is similar to the link below.

    Hello, 
     
    Thank you for your response. I have checked that post. And actually, it is not the same thing. In my case, I want to create only one username/password for everyone as a Guest, but if the device is disconnected from the network for any reason, (Ex: cable disconnection from the network) I would like to force the user to re-authenticate.  
    In my case, several users/devices would use the same guest account at the same time.

    it's not possible. Fortigate will keep the user until idle-timeout time.

    Or you can check the user monitor list with the REST-API and de-auth the ip address that does not respond to ping.
