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 1-3 illustrates the general process of server initialization and response to an
authentication request.
