A wireless network uses a RADIUS server that is connected to an authenticator, which in turn connects to a supplicant. Which of the following represents the authentication architecture in use?
802.1X uses three terms that you need to know. The user or client that wants to be authenticated is called a supplicant. The actual server doing the authentication, typically a RADIUS server, is called the authentication server. And the device in between, such as a wireless access point, is called the authenticator.
802.1X is a standard for port-based network access control (PNAC), but it does not inherently provide any single sign-on functionality.
Mainly a server that is a supplicant connected to authenticator, which is switch or access point. And 802.1x is used to authenticate users between RADIUS server and an access point or a switch.
Interesting...The first word that jumped out to me was "supplicant" The IEEE 802.1X standard uses the term "supplicant" to refer either to hardware or to software. <wikipedia>
