After enable MAC address-prioritized Portal authentication, some user cannot reconnect after lock and unlock screen.

Hi all,

This is a case about portal authentication.

[Issue Description]

After enabling MAC address-prioritized Portal authentication, some users cannot reconnect after lock and unlock the screen.

[Analyze]

The root cause is that the SSID tpmpad that uses MAC address authentication is configured on the AC with local database. After the terminal is connected to this SSID, the terminal will remember it. After the terminal is locked and unlocked, the terminal connects to this SSID. But if the terminal does not have a local account, the authentication fails. After the authentication fails, the terminal will be silent for 60 seconds. In this case, the terminal cannot perform MAC address-prioritized Portal authentication.
