We have ACS 4 and we use a 4404 wireless lan controller. In the past month we've been experiencing outages for our wireless clients. We get alert messages from ACS like "Auth server down: Could not change Password" or "Test Timed out for service: CSRadius & Test Timed out for service: CSTacacs". Then users start calling in reporting that they are down.
I did a search and keep finding this "Error Message Auth server down: Could not change Password
Explanation CSMon could not change the password of the test account.
Recommended Action No action required."
Can anyone provide more information on what could be going on and why this alert which says no action required keeps showing up and then wireless goes down?
