HP-UX AAA Server A.08.01 administrator's guide (T1428-90072, May 2010)

invoke the SQL Access AATV to enter values based on the information stored
in a database table.
2. The CLIENT AATV is invoked through the FSM, and the action function of the
CLIENT AATV is executed. The action function of the CLIENT AATV performs
two major functions. One, it places the current client request in the message queue
for client messages. Two, it generates another empty RADIUS request and places
it in the initial state of the FSM. Similarly, new client requests are generated and
placed in the message queue successively, thereby resulting in a loop. You can
configure the number of new client requests that must be generated by specifying
the value in the client_max_requests field of the aatv.CLIENT block, within
the aaa.config file.
3. After the client requests are assigned values, they are sent to the target host by the
ReplySend AATV. Subsequently, the request waits for a response. If the request
is timed out, it is retransmitted based on the configured retransmission interval
and the maximum number of retransmissions.
4. One or more AATVs are invoked to perform the post-processing action. For
example, the SQL Access AATV can be invoked to modify the database table
based on the response received.
Figure 19-1 illustrates the working of the client functionality.
