Setting up TACACS+ between Cisco ACS and 4402 WLC using the below configuration guide.
Authenication is failing on the WLC. Currently getting the below error message on the Cisco ACS server (Reports and activity > failed attempts)
Message Type: Author Failed
Author-Failure-Code: Service denied
Author-Data: service=ciscowlc protocol=common
Anybody have any idea to resolve this problem.
