A supplicant, in some contexts, refers to a user or to a client in a network environment seeking to access network resources secured by the IEEE 802.1X authentication mechanism. But saying "user" or "client" over-generalizes; in reality, the interaction takes place through a personal computer , an Internet Protocol (IP) phone, or similar ...
MS-CHAP is used as one authentication option in Microsoft's implementation of the PPTP protocol for virtual private networks.It is also used as an authentication option with RADIUS [2] servers which are used with IEEE 802.1X (e.g., WiFi security using the WPA-Enterprise protocol).
Windows defaults to not responding to 802.1X authentication requests for 20 minutes after a failed authentication. This can cause significant disruption to clients. The block period can be configured using the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\dot3svc\BlockTime [ 15 ] DWORD value (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\wlansvc\BlockTime for ...
A basic form of NAC is the 802.1X standard. Network access control aims to do exactly what the name implies—control access to a network with policies, including pre-admission endpoint security policy checks and post-admission controls over where users and devices can go on a network and what they can do.

The Lightweight Extensible Authentication Protocol (LEAP) method was developed by Cisco Systems prior to the IEEE ratification of the 802.11i security standard. [3] Cisco distributed the protocol through the CCX (Cisco Certified Extensions) as part of getting 802.1X and dynamic WEP adoption into the industry in the absence of a standard.
It is the default authentication method in Windows 2000 and later. The authentication process itself is much more complicated than in the previous protocols - Kerberos uses symmetric key cryptography, requires a trusted third party and can use public-key cryptography during certain phases of authentication if need be.

802.1X clients and servers developed by specific firms may support other EAP types. This certification is an attempt for popular EAP types to interoperate; their failure to do so as of 2013 is one of the major issues preventing rollout of 802.1X on heterogeneous networks. Commercial 802.1X servers include Microsoft Network Policy Server and ...
