At work we used Cisco ACS 4.1 to manage the WiFi accounts at work.
Under Reports & Activities we select "Disabled Accounts" and get the following error
"No disabled accounts or accounts hidden due to access restrictions"
We are the administrators and should have full access, and we've looked at the permissions and have all options checked, so completly unsure!
I will admit, it's not a system we daily use nor are we aware of any Cisco CLI's etc, as it's something were not trained in doing, but the ACS is somewhat user friendly
If we get "Disabled Accounts" to display again in ACS, is there a way to delete in one hit? - But this is only a nice thing, but we really need it to list disabled accounts
