TACACS
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 through user names and
user-defined passwords.
• Authorization:
Performed at login. When the authentication session is completed, an
authorization session starts using the authenticated user name. The TACACS server
checks the user privileges.
