administrative control over the authentication and authorization processes. TACACS+ allows for a single access control server (the TACACS+ daemon) to provide authentication, authorization, and accounting services independently.

There is a draft RFC detailing this protocol. Further information on configuring remote TACACS+ servers can be found at the following sites:
