Is the use of a AAA Server limited to TACASC+, RADIUS, or Diameter, or is the functionality of AAA met by the seperation of the processes used in AAA (Authentication, Authorization, and Auditing).
Example: For remote access to the company network, remote users will access through a SSL VPN, requiring a username/password, which utilizes Active Directory (Kereros) and LDAP authentication methods. Authorization is controlled through role based access for access to specificed resources. Auditing is also tracked by the SSL VPN device, logging date/time, session duration, termination type, etc.
Would that scenerio meet the requirement for AAA? Or does AAA require the use of, as above, TACASC+
Software/Hardware used: Active Directory, LDAP, F5 SSL VPN
