TACACS+ question

I am setting up a secure dial in system using CiscoSecure ACS for NT. We will be using TACACS+ and secure id tokens.

I know I can define multiple TACACS servers on the NAS (2600) but if the first server defined fails the user request, will the second TACACS server then be queried? I think if the first fails then the connection is dropped but I cant seem to confirm this.

Anybody out there know the answer?


Re: TACACS+ question

There are two issues really; whether the first server doesn't respond at all, in which case the NAS will automatically try the next host after the timeout; and whether the first server does reply but with a FAIL, in which case the user is dropped. In other words, the second server is used as a backup and not as an additional authentication attempt.

Re: TACACS+ question

If the first server fails, i.e. rejects the request you are done, it only looks to the secon d server if the first server fails to respond at all.
