Core issue
The Authentication, Authorization, and Accounting (AAA) server does not respond to the authentication request from the PIX Firewall before the authentication request times out.
Resolution
Troubleshoot the network between the PIX and the AAA server or the AAA server itself.
If the network traffic is extremely high, or packet loss is present, increase the timeout for authentication requests. From the PIX command line interface, issue the aaa-server group_tag (if_name) host server_ip key timeout seconds command and increase the time in seconds to a larger value (try 20 or 30 seconds).
