UM Mac-Authentication with automatic login

Is it possible to configure a user within User Manager to be automatically logged in by using their mac address as the username? I tried the following:

/tool user-manager user add username=XX:XX:XX:XX:XX:XX subscriber=hs_admin

But I still have to enter my own mac address as the login username when redirected to the hotspot webpage.

My hotspot profile is set to “use-radius=yes” and radius is set to the hotspot service.

Have you changed login-by to login-by=mac ? (in ip hotspot profile)

Yes. My hotspot login-by is set to login-by=mac,cookie,http-chap
