I was wondering... If anyother 3rd Party TACACS server can be used to integerate with LMS to play the same role as ACS... or it just ACS that works with LMS
My requirement is to use the customized groups feature....
Pure ACS integration which provides centralized authorization, device limiting, custom roles, etc. can only be done with CiscoSecure ACS.
However, for the purpose of centralized authentication, you can use any TACACS+ server (including the Open Source tac_plus daemon). You can also use services such as AD and Radius to provide external authentication.
