This section is applicable to HSG (HSA/CMG/MAP have no built-in RADIUS server).

There are a few commonly used interchangeable names, which are all referring to the same function that helps to authenticate user access, issues access policies for NAS/mbox to enforce and stores user access records, they are called differently at different places but all mean the same thing:

• UAM Server (User Access Manager)

• AAA Server (Authentication, Authorization, Accounting)

• RADIUS Servers (Remote Authentication Dial-In User Service)

In most of our technical documentation, we use the name RADIUS. Please refer to the respective link below for more details.
