Auth_providers, is it a relic?

I’ve tried following the docs:

But I must be missing something.

I entered this in my test HA

homeassistant:
  auth_providers:
    - type: trusted_networks
      trusted_networks:
        - x.y.z.v/32
      trusted_users:
        x.y.y.v: kiosk
      allow_bypass_login: true
    - type: homeassistant

and it starts up in Recovery mode.

The idea was that my kiosk would just open a predefined display.
I don’t understand what I’ve missed from the docs or is trusted_networks no longer available?

Arrhhh, of course I noticed that the docs are right, it’s the ID of the user, not the username that is needed, so after correcting that to the long hexadecimal number, it worked like a charm!
