Supplicant (computer)
Encyclopedia
The term supplicant is used in the IEEE 802.1X
standard, where the supplicant is an entity at one end of a point-to-point LAN segment that seeks to be authenticated by an authenticator
attached to the other end of that link. In practice, a supplicant is a software application installed on an end-user's computer. The user invokes the supplicant and submits credentials to connect the computer to a secure network. If the authentication is successful, the authenticator typically allows the computer to connect to the network.
