RADIUS Server User Authentication Settings

In order for client authentication and accounting to be done on a RADIUS server, the RADIUS server must be configured with four pieces of data for each user.

User name

Login password

Group configuration

Tunnel secret

The user name is kept in the User-Name attribute in the RADIUS server and the login password is kept in the Password attribute. The group configuration is kept in attribute number 77 of the RADIUS database, and the tunnel secret is kept in attribute number 69. These two attribute numbers must be configured in the RADIUS server’s dictionary file.

The RADIUS server will also log the real IP address of the client and the IP address assigned to the client by the IntraPort as it begins to account for the client. To use this feature, the two attribute numbers for these two IP address strings must also be configured in the RADIUS server’s dictionary file and in the RADIUS section of the IntraPort’s configuration.

The following is an example for a Livingston RADIUS server dictio- nary file:

ATTRIBUTEClient-Real-IP

66

string

ATTRIBUTEClient-Assigned-IP

67

string

ATTRIBUTEVPN-Password

69

string

ATTRIBUTEVPN-GroupInfo

77

string

The following is a sample RADIUS user database entry from a Living- ston RADIUS server.

User-Name = corpauser

Password = radius login

VPN-Password = abc

VPN-GroupInfo = CorporateA

After making and saving these changes, you must restart the RADIUS server in order for it to recognize the new settings.

ϖNote: Refer to the user manual for your RADIUS server for the exact format of dictionary and user database entries.
