802.1x Configuration for IAS and
Windows Clients
This appendix provides examples of how to configure a Microsoft Internet Authentication Server, and a Windows
XP wireless client for 802.1x authentication with the controller (see Chapter 9, “802.1x Authentication” for
information about configuring the controller).
For more information about configuring computers in a Windows environment for PEAP-MS-CHAPv2 and EAP-
TLS authentication, see the Microsoft document Step-by-Step Guide for Setting Up Secure Wireless Access in a
Test Lab, available from Microsoft’s Download Center (at www.microsoft.com/downloads). Additional
information on client configuration is available at http://www.microsoft.com/technet/prodtechnol/winxppro/

Configuring Microsoft IAS
Microsoft Internet Authentication Server (IAS) provides authentication functions for the wireless network. IAS
implements the RADIUS protocol, which is used between the Dell controller and the server. IAS uses Active
Directory as the database for looking up computers, users, passwords, and group information.
RADIUS Client Configuration
Each device in the network that needs to authenticate to a RADIUS server must be configured as a RADIUS
client. You must configure the Dell controller as a RADIUS client.
To configure a RADIUS client:
1. From your windows server, navigate to Start > Settings > Control Panel > Administrative Tools>Internet
Authentication Service.
2. In the Internet Authentication Service window, select RADIUS Clients.
Figure 128 IAS RADIUS Clients
3. To configure a RADIUS client, select Action > New RADIUS Client from the menu at the top of the
window.
Note: The steps to perform this task may very depending on the version of Windows currently running on your server. For complete
details on configuring Windows IAS, refer to the Windows documentation available (at www.microsoft.com/downloads).
