I have setup WCS logins to be managed by ACS 4.2 . I was looking over the docs and I appear to be missing something because I can't find any documentation on doing the same to the controllers. I did successfully lock myself out of the WiSM in the lab during some testing. I had to pull the plug on the lab ACS to allow local login.
Any Thoughts ?
Take a look at the configuration guide for the WLC. It gives you the attributes you need to configure on the ACS for TACACS.
