What error are you seeing on the tacacs server? Did you define enable privilege 15 on the tacacs server?

What is the code of tacacs/ACS are you running?

Can you paste the output of

debug tacacs

debug aaa authen

debug aaa autho

It is most likely a configuration or rechability issue. Double check

that you've got the right IP in the config, and that there's nothing

interfering with UDP between the two. With tacacs, it's good idea

to have known backup telnet & enable passwords, this same kind of

thing can happen when you have a badly congested link or some kind of

network problem and life is better when you can get into the router.

cannot be a reachability issue as tacacs is processing the request and throwing "authorization failed". Also, I didn't understand when you say "that there's nothing interfering with UDP between the two" because tacacs works at tcp 49.
