This document defines two EAP extended key usage values and a public
key certificate extension to carry Wireless LAN (WLAN) System Service
Several Extensible Authentication Protocol (EAP) [EAP] authentication
methods employ X.509 public key certificates. For example, EAP-TLS
[EAP-TLS] can be used with PPP [PPP] as well as IEEE 802.1X [802.1X].
PPP is used for dial-up and VPN environments. IEEE 802.1X defines
port-based, network access control, and it is used to provide
authenticated network access for Ethernet, Token Ring, and Wireless
LANs (WLANs) [802.11].
Automated selection of certificates for PPP and IEEE 802.1X clients
is highly desirable. By using certificate extensions to identify the
intended environment for a particular certificate, the need for user
input is minimized. Further, the certificate extensions facilitate
the separation of administrative functions associated with
certificates used for different environments.

RFC 3770 PPP and WLAN May 2004
IEEE 802.1X can be used for authentication with multiple networks.
For example, the same wireless station might use IEEE 802.1X to
authenticate to a corporate IEEE 802.11 WLAN and a public IEEE 802.11
"hotspot." Each of these IEEE 802.11 WLANs has a different network
name, called Service Set Identifier (SSID). If the network operators
have a roaming agreement, then cross realm...
