AAA Environment Components
The AAA environment consists of the following interoperating components:
• HP-UX AAA Server Daemon, Libraries, Configuration Files, and Utilities: Perform the
authentication, authorization, and accounting functions to process requests.
• Web Based Server Manager Administration Utility: Configures and manages the servers. The
Server Manager can retrieve logfile messages and statistics from HP-UX AAA Servers.
• Supplicants: Application software that request access to network services via RADIUS clients.
• RADIUS Clients: Communicate with the HP-UX AAA Server using the RADIUS protocol standard.
They serve as enforcement points to control access to network services.
• External Services: Interoperate with the HP-UX AAA Server to provide user profile storage
(databases) and other services such as DHCP (IP address management) and SNMP (network
management).
Figure 99 depicts the AAA environment and components. Troubleshooting the AAA environment
involves determining the component that caused the problem and taking the necessary corrective
actions.
