I am able to login to my router VIA TACACS+ server. My username and password doesnot work with enable mode. When I do enable after login to user prompt; it just throws me "Authentication failed" message.
AAA commands used
aaa authentication login default group tacacs+ local
aaa authentication enable default group tacacs+ enable
I set up TACACS+ server and key as it has been working with login.
I really appreciate if any one can help in this issue.
I don't have ACS server in hand right now. But I believe that you need turn on something on ACS server so that you can have TACACS+ to authenticate on enable password. Just enable all TACACS+ feature under "Interface" then go throught each feature you have under user configuration to see which one might be related to it.
