one of our ASAs is having problems authenticating against our tacacs server. We can run the test authentication feature fine and the ASA can ping the server. However when I try to authenticate I see this in the log:
4 Aug 28 2007 09:30:31 409023 Attempting AAA Fallback method LOCAL for Authentication request for user [someuser] : Auth-server group [acsserver] unreachable
On the ACS server I don't see any failed attmpets on the logs. All of our other devices work fine including a few other ASAs. Th eonly difference with this guy is that its running 8.0 software. I double checked the shared key and its okay (well it should be fine since I can run the test fine). Any ideas?
