AUTH packet cannot used implied properties as there is a require property

From Will Lisac

It’s unclear to me if the "Authentication Method” property must always be included. I see two potentially conflicting statements.

3.15.2.1 Authenticate Reason Code
…
The Reason Code and Property Length can be omitted if the Reason Code is 0x00 (Success) and there are no Properties. In this case the AUTH has a Remaining Length of 0.

3.15.2.2.2 Authentication Method
…
It is a Protocol Error to omit the Authentication Method or to include it more than once
