RADIUS Server

The RADIUS server component provides user authentication and accounting services. Remote Access Dialup User Service (RADIUS) is the protocol used by Network Access Servers (NAS) to authenticate remote users who connect to the network.The information provided to the NAS in the access request is checked against the information stored in the directory.

All NAS devices available on the market can be configured to use the RADIUS server in Sun Directory Services to authenticate remote users.

The RADIUS server function is performed by the dsradiusd daemon. A full description of the RADIUS architecture is provided in Chapter 7, Using the RADIUS Server.
