Different user showing on Fortinet bar

[DarwinPH]

Greetings!

We have setup captive portal on our network using local authentication. For some reason, some devices that are suppose to login first already show the Fortinet bar with a user logged in. Any ideas on why this happens?

Thank you all in advance!

Hi DarwinPH, just a wild guess: don't you have some users/devices behind NAT from FortiGate point of view? So they share the same IP...

Fishbone, thank you for your response! Got a hint on the solution from it - 'share the same IP'. Our DHCP lease time is way shorter that the idle time out for the captive portal to deauthenticate the users.
