SUMMARY

This article describes how to set up Microsoft Internet Authentication Server (also known as Microsoft Radius Server) for authentication to a third-party ODBC data source. The purpose of this article is to walk you through the process of setting up a sample ODBC source (in this case SQL Server is used) and Microsoft Radius Server.

How to set up a SQL Server 6.5 database for Radius authentication:

Install SQL Server 6.5 with Service Pack 4.

For Language, choose 850multi-lingual.

For Sort-Order, choose Alternative Directory Order, Case-Insensitive.

For Network Options, choose Named Pipes.

When SQL Server is installed, register the database and create two database devices and one database with a name of your choice.

Create a new table called "Network_Users" (NOTE: it must be called "Network_Users").

The ODBC table should be in the following format.


   Table Name: Network_Users

   For an Access ODBC Source:

   Name          Type   Size

   UserName      Text    50
   Password      Text    64

For a SQL ODBC source:


   Name          Type     Size

   UserName      varchar   50
   Password      varchar   64

To register and configure an ODBC authentication server and Database, perform the following:

On the Radius Server, click the Authentication Providers tab.

Select ODBC Authentication and click Configure.

Enter a description of the authentication database in the Authentication database description box and click Configure Database.

Click the Machine Data Source tab and verify that you have already configured a data source.

If you have already configured a data source, locate the data-source name and click OK.

-or-

If you are creating a new data source, click New and follow the Create New Data Source Wizard. Choose the ODBC table "network_users_" that you set up in the previous steps.

The ODBC data source should be configured as a system Data Source Name (DSN). Users should now be able to log in through Radius via SQL Server.
