I installed ACS 4.2 AAA server and wanna to do authenticate user against TACACS. i found one java client library (http://sourceforge.net/projects/jnetlib/to do the same. my query is that is there any another Open source java client library available to authenticate user against Tacacs or provided by Cisco?
Please explain more about what you are trying to authenticate. Are you authenticating to the switch? Or is this the user that plugs into a switch port and needs to be authenticated? If its the latter then you need to configure dot1x authentication and this only uses RADIUS and not TACACS. I am unclear on what you mean by java client library-
If the user needs to authenticate on a switch port (dot1x) then he needs a dot1x supplicant to do this - Cisco's supplicant is the CSSC-Cisco secure services client.
