| CiscoSecure ACS can be configured to use a Windows NT user database. A request to the NAS, TACACS+ or RADIUS is directed to the Windows NT user database for authentication and authorization. If approved, NT grants permission to the client. A response is returned to CiscoSecure ACS and authorizations are assigned. Accounting information is logged through the use of the NT user database. Usernames and passwords are the same for network and dial-up access.
