We have our Ciscoworks server set to authenticate to our ACS server (Non-ACS and Tacacs+). In other words, authenticate to ACS but do not register modules to ACS (controlled on the server). We had some network issues where we could not ping the ACS servers. When that happened I noticed that the Authentication mode is now "Tacacs+ (fallback Mode). How can I get that out of that mode and back into authentication "Tacacs+"
