Cisco Secure ACS System Description
Cisco Secure ACS network security software helps you authenticate users by controlling access to a AAA client—any one of many network devices that can be configured to defer authentication and authorization of network users to a AAA server. Cisco Secure ACS operates as a set of Windows services that control the authentication, authorization, and accounting of users accessing networks. Cisco Secure ACS operates on Windows 2000 Server. Windows 2000 Advanced Server and Windows 2000 Datacenter Server are not supported. Cisco Secure ACS can run on a domain controller or a member server.

Note If you install Cisco Secure ACS on a member server and want to authenticate users with a Windows Security Account Manager user database or an Active Directory user database, there is additional Windows configuration required after you have installed Cisco Secure ACS. For more information, see Windows Authentication from a Member Server.
