HP-UX AAA Server Architecture
The HP-UX AAA Server architecture consists of the following components:
• Configuration files. Files to provide the information necessary for the server to perform
authentication, authorization, and accounting requests for your system. In most cases, these
files can be modified by using the Server Manager.
• AATV plug-ins. Dynamically loaded libraries that perform discrete actions, such as initiating
an authentication request, replying to an authentication request, or logging an accounting
record.
• The radiusd software engine, which includes the Finite State Machine (FSM) and associated
routines. At server startup, the FSM reads instructions from the state table in the /etc/opt/
aaa/radius.fsm configuration file. The state table outlines what AATV actions to call and
what order to call them in.
When the server is initialized, it loads and initializes the AATV plug-ins. It also reads the
configuration files to initialize the data required for the actions to execute according to the
application's requirements.
Figure 3 illustrates the general process of server initialization and response to an authentication
request.
