Finally the acs box has joined the domain now. What are the neccessary step required for authentication via the domain. eg, what do I need to do on the acs box so that domain users can be authenticated to log on to devices?

i have done the neccessary tacacs config on the host but they fail authentication.

Is there anything like group mapping or what?

In a summary, what are the configuration steps on the acs after joining it to the domain?

thanks all.
