CiscoSecure ACS 4.2 RADIUS Server and “Add AAA Client Errors” Message
Recently I was testing Cisco’s CiscoSecure ACS 4.2 for RADIUS authentication for Cisco VPNs. The ACS server is configured through a web browser. I could start the browser and get into the management web site, however when I tried to add an AAA/RADIUS client I would receive the message “Add AAA Client Errors”:
What really perplexed me was the warning that the “Shared Secret” was blank, when in fact I had entered a value for it.
Turns out that you need to have the Java Runtime installed for the management web site to work properly. Once that was install, everything worked great.
