IAS logs only accounting requests sent by the RADIUS client. If the RADIUS client is not configured for RADIUS accounting, accounting requests for that client are not logged. • Authentication Requests Enable or disable the logging of authentication requests in the IAS log file. • Periodic Status Enable or disable the logging of interim accounting requests in the IAS log file.

This message acknowledges the successful receipt and processing of the Accounting-Request message. For Point-to-Point Protocol (PPP) authentication protocols such as Password Authentication Protocol (PAP), Challenge Handshake Authentication Protocol (CHAP), Microsoft Challenge Handshake Authentication Protocol (MS-CHAP), and MS-CHAP version 2 (MS-CHAPv2), the results of the authentication negotiation between the access server and the access client are forwarded to the RADIUS server for verification in the Access-Request message.

0 domain, an Active Directory–based domain, or the local SAM as your user account database for access clients. • You use the Windows 2000 Server or Windows Server 2003 Routing and Remote Access service on multiple dial-up servers, VPN servers, or site-to- site routers; and you want to centralize both the configuration of remote access policies and accounting of connection information. • You outsource your dial-in, VPN, or wireless access to a service provider. The access servers use RADIUS to authenticate and authorize connections that are made by members of your organization.
