Dear @EmiTp,

is there a possibility to logout the local user using a portal hotspot?

In a school I want to use same pc connetter to the portal SSID but with different local users after 2 hours. 

After the client connects through portal authentication, you could unauthorize the client from the Clients page on the SDN Controller.

With that option, perhaps you can force the PC connected to the portal SSID to reconnect with a different local user.

If your purpose is to make the clients connect only for 2 hours each time, you may configure Voucher using portal hotspot instead.

For the Voucher portal, we can custom the Duration to specify the valid period for the voucher code(s).

Dear @Emitplink,

I would like to logout the users from itself using local user as authentication, is possible?

Could you please be more specific? I would like to ensure I got your problem correctly.

What's the purpose of doing this? Can you give me the application scenario and network requirements?
