This service determines, from the credentials provided by the supplicant, whether the
supplicant is authorized to access the services provided by the authenticator.

authentication of the entity attached to the other end of that link.
Supplicant: An entity at one end of a point-to-point LAN segment that is being authenticated
by an authenticator attached to the other end of that link.
