I was running ACS2.6 & using TACACS+ to authenticate dial in users & access to routers. When dial up users tried to telnet to a router they received an authorisation failure (EXEC box not ticked) if they tried to log in. Since upgrading to ACS3.1 they now log in & get a command line. They cannot get into enable mode however I don't like the fact they can actually get onto the routers.
