D-Link Unified Access System Software User Manual 12/10/09 TACACS+ SETTINGS D-Link software provides Terminal Access Controller Access Control System (TACACS+) client support. TACACS+ provides centralized security for validation of users accessing the device. TACACS+ provides a centralized user management system, while still retaining consistency with RADIUS and other authentication processes. TACACS+ provides the following services: • Authentication: Provides authentication during login and via user names and user-defined passwords. • Authorization: Performed at login. Once the authentication session is completed, an authorization session starts using the authenticated user name. The TACACS+ server checks the user privileges. The TACACS+ protocol ensures network security through encrypted protocol exchanges between the device and TACACS+ server. The TACACS+ folder contains links to the following web pages: • "TACACS+ Configuration" • "TACACS+ Server Configuration" TACACS+ CONFIGURATION The TACACS+ Configuration page contains the TACACS+ settings for communication between the switch and the TACACS+ server you configure. To display the TACACS+ Configuration page, click LAN > Security > TACACS+ > Configuration in the navigation menu.
