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.
