Setting up Radius Authentication

Chapter 6 - Basic Configuration Guide

If you are using a RADIUS server for user authentication, you must set up the IntraPort Enter- prise-8 to communicate with a RADIUS server and also set some special parameters in the RADIUS server itself

Setting the IntraPort Enterprise-8 for a RADIUS Server

Just a few basic settings are required for the IntraPort Enterprise-8 to communicate with a RADIUS server:

•Primary server IP address

•Secret

•VPN password attribute number

•VPN group attribute number

CV: Use the RADIUS Configuration Dialog Box.

TB: Use the configure command and set the PrimAddress, Secret, VPNPassword and VPNGroupInfo keywords in the RADIUS section.

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 pass- word 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 Enterprise-8 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 configura- tion.

The following is an example for a Livingston RADIUS server dictionary file:

ATTRIBUTEClient-Real-IP66 string

ATTRIBUTEClient-Assigned-IP67 string

ATTRIBUTEVPN-Password69 string

ATTRIBUTEVPN-GroupInfo77 string

The following is a sample RADIUS user database entry from a Livingston RADIUS server:

User-Name = corpauser

Password = "radiuslogin"

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.

ϖNote: Although MacRADIUS servers offer a GUI, the custom attribute settings will require that you enter users in the Users text file. See the user manual for your server for more infor- mation on exporting, editing and importing the Users text file.

In addition to the RADIUS server settings, the user name, login password and tunnel secret must match the settings for each user in the User Properties window of the VPN Client. The group configuration must match one of the VPN group configurations in the IntraPort Enter- prise-8’s configuration.
