Obtaining a TLS-EAP certificate for a client
Important If you want to use IEEE 802.1x mode with EAP-TLS certificates for authentication and authorization of clients, you must have an external RADIUS server and a Public Key Authority Infrastructure (PKI), including a Certificate Authority (CA), server configured on your network. It is beyond the scope of this document to describe the configuration of the RADIUS server, PKI, and CA server. Consult the documentation for those products.
Some good starting points available on the Web for the Microsoft Windows PKI software are: “How to Install/Uninstall a Public Key Certificate Authority for Windows 2000" at http://sup-port.microsoft.com/default.aspx?scid=kb;EN-US;231881 and “How to Configure a Certificate Server” at http://support.microsoft.com/default.aspx?scid=kb;en-us;318710#3.
Wireless clients configured to use either “WPA with RADIUS” or “IEEE 802.1x” security modes with an external RADIUS server that supports TLS-EAP certificates must obtain a TLS certificate from the RADIUS server. This is an initial one-time step that must be completed on each client that uses either of these modes with certificates. In this procedure, we use the Microsoft Certificate Server as an example.
To obtain a certificate for a client, follow these steps.

Where IPAddressOfServer is the IP address of your external RADIUS server or of the Certificate Authority (CA), depending on the configuration of your infrastructure.
