Chapter 6 Using EAP Authentication

Using EAP-TLS

After Profile Selection or Card Insertion

After you (or auto profile selection) select a profile that uses host-based EAP authentication and you

configure the card in Windows (provided Windows is using the Microsoft 802.1X supplicant) for

EAP-TLS authentication or you eject and reinsert the client adapter while this profile is selected, follow

the steps below to EAP authenticate.

Step 1 If your computer is running Windows XP and a pop-up message appears above the Windows system tray

informing you that you need to accept a certificate to begin the EAP authentication process, click the

message and follow the instructions provided to accept the certificate.

Note You should not have to accept a certificate for future authentication attempts. After you accept

one, the same certificate is used subsequently.

Step 2 If a message appears indicating the root certification authority for the server’s certificate, and it is the

correct certification authority, click OK to accept the connection. Otherwise, click Cancel.

Step 3 If a message appears indicating the server to which your client adapter is connected, and it is the correct

server to connect to, click OK to accept the connection. Otherwise, click Cancel.

Step 4 The client adapter should now EAP authenticate. To verify authentication, double-click My Computer,

Control Panel, and Network Connections. The status appears to the right of your Wireless Network

Connection. Click View and Refresh to obtain the current status. If the client adapter is authenticated,

the status reads Authentication succeeded.

After a Reboot or Logon

After your computer reboots or you log on using your Windows username and password, the EAP

authentication process begins automatically and the client adapter should EAP authenticate.

To verify authentication, double-click My Computer, Control Panel, and Network Connections. The

status appears to the right of your Wireless Network Connection. Click View and Refresh to obtain the

current status. If the client adapter is authenticated, the status reads Authentication succeeded.
