Hello Everyone.
I'm not an expert in AAA Authentication that's why I'm here..
We 3 routers, 1 of which works with Authentication and the other 2 that don't.
We have configured the following:
aaa new-model
!
!
aaa authentication login default group tacacs+ local
aaa authorization exec default group tacacs+ if-authenticated.
The problem is that when I try to connect using the TACACS server username and password it gives me a generic error message the classic.
% Athentication Failed
But if I try the local username and password it works..
How come, it's not a problem of routing because the one that works uses the same exit point to reach the server as the one that doesn't, the only difference that exists is the IOS is different..
Can anyone point me in the right direction? Please and thank you
