Service Provider Configuration
The service provider can use IAS as a RADIUS server if the service provider is using a Windows NT Server 4.0 domain, an Active Directory directory service domain, or the local Security Accounts Manager (SAM) as the user account database for its customers.
Figure 13-2 shows the configuration of the service provider that is using IAS RADIUS servers.

To configure the primary and secondary IAS RADIUS server of the service provider to allow wireless access at the WISP for its customers, see Chapter 8 (for EAP-TLS authentication) or Chapter 10 (for PEAP-MS-CHAP v2 authentication).
