Microsoft IAS RADIUS Server
The Internet Authentication Service (IAS) is a Microsoft implementation
of the Remote Authentication Dial-In User Service (RADIUS) protocol.
The procedures in this section describe how to configure the Dominion
SX to use an IAS server.
Configure the Dominion SX to Use an IAS RADIUS Server
The tasks to set up the Dominion SX unit to use an IAS RADIUIS server
are:
 Configure a Primary Radius Server (and optional secondary Radius
server).
 Configure a Radius port.
 Configure a secret (shared secret) that will be matched in the IAS
client configuration within IAS.
The following example shows a simple setup based on a new IAS
installation.
Note: If the IAS setup already exists, these instructions may not apply
exactly as shown.
