Using RADIUS to Authenticate Users

This section provides a description of RADIUS and explains how to configure PortServer TS 8/16 to use RADIUS.

What is RADIUS?

RADIUS (remote authentication dial-in user service) is a method of maintaining a database of profiles of dial-in users. These profiles can include login and password information, as well as other user attributes.

RADIUS Components

RADIUS requires two components, an authentication host server and client protocols. The PortServer TS 8/16 implements the client protocol. A host must implement the authentication server application.

RADIUS Table Key

The numbers in the following tables have the following meaning:

#	Meaning
0	This attribute must not be present.
0+	Zero or more instances of this attribute may be
	present.
0-1	Zero or one instance of this attribute may be
	present.

1Exactly one instance of this attribute must be present.

RADIUS Attributes (RFC 2138) Supported

The following attributes are supported in the Digi PortServer TS 8/16 RADIUS client implementation.

Request	Accept		Reject	Challenge	#	Attribute
1	0	0		0	1	User-Name
0-1	0	0		0	2	User-Password
0-1	0	0		0	3	CHAP-Password
0-1	0	0		0	4	NAS-IP-Address
0-1	0	0		0	5	NAS-Port
0-1	0-1	0		0	6	Service-Type
0-1	0-1	0		0	7	Framed-Protocol
0-1	0-1	0		0	8	Framed-IP-Address
0-1	0-1	0		0	9	Framed-IP-Netmask
0	0-1	0		0	10	Framed-Routing
0	0+	0		0	11	Filter-Id
0	0-1	0		0	12	Framed-MTU
0+	0+	0		0	13	Framed Compression
