Xsupplicant is a supplicant

Supplicant (computer)

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...
