While Microsoft's documentation states that authentication with Entra ID is possible, the evidence identified irregularities in authentication procedures for version 20, as confirmed by Microsoft representatives, when also checking with them.
Attached to the official Microsoft documentation web page that states the authentication of version 20 with Entra Id.
