The supplementary RADIUS Accounting specification [1] also provides accounting mechanisms, thus delivering a full AAA protocol solution. However, RADIUS has two substantial shortcomings.
When a server running NPS is a member of an Active Directory Domain Services (AD DS) domain, NPS uses the directory service as its user account database and is part of a single sign-on solution. The same set of credentials is used for network access control (authenticating and authorizing access to a network) and to log on to an AD DS domain. [3]
Authentication requests and accounting information are forwarded by the V-AAA to the H-AAA, either directly or through a B-AAA. Current AAA servers communicate using the RADIUS protocol. As such, TIA specifications refer to AAA servers as RADIUS servers. While at one point it was expected that Diameter was to replace RADIUS, that has not happened.
RADIUS Accounting Flow. Accounting is described in RFC 2866. When network access is granted to the user by the NAS, an Accounting Start (a RADIUS Accounting Request packet containing an Acct-Status-Type attribute with the value "start") is sent by the NAS to the RADIUS server to signal the start of the user's network access. "Start" records ...
