We have the Cisco Secure ACS v 3.2. There is a devices that we recently discovered is not added into the network configuration on the ACS. This device running IOS 12.2(29) does have all of the correct tacacs settings that should allow it to authenticate via Tacacs.
So basically, the ACS is allowing users to use this device to login, even though it's not in the Network Config.
When we look at the Logged-in Users report, it show the host name as "Tacacs+ Default". We aren't sure what that is supposed to mean, and why it's allowing it.
Thank You for your time,
