How do I configure Oracle RADIUS

To configure Oracle RADIUS in an Oracle database, you will need to do the following:
  1. Install the Oracle RADIUS package: The Oracle RADIUS package is a set of database objects and PL/SQL procedures that provide support for RADIUS authentication and accounting. To install the package, you will need to run the dbms_radius_install.sql script as the database administrator.
  2. Create a RADIUS client: A RADIUS client is a device or system that sends RADIUS requests to the database. To create a RADIUS client, you will need to run the dbms_radius.create_client procedure, passing in the client's IP address and shared secret as arguments.
  3. Create RADIUS users: RADIUS users are the users who will be authenticated by the database using RADIUS. To create a RADIUS user, you will need to run the dbms_radius.create_user procedure, passing in the user's username and password as arguments.
  4. Configure the database listener: The database listener is a process that listens for incoming client connections and dispatches them to the database. To configure the listener to support RADIUS authentication, you will need to add the RADIUS authentication adapter to the listener configuration file.
  5. Test the RADIUS configuration: Once you have completed the above steps, you can test the RADIUS configuration by attempting to connect to the database using a RADIUS-enabled client and a valid RADIUS user. If the connection is successful, your RADIUS configuration is working as expected.

Configure and use RADIUS adapter

1) The first step is to select RADIUS as one of the supported security protocols. when installing Oracle Advanced Security.

2) The second step is to configure Network Services to use RADIUS for authentication. Do this by adding the lines you see here into the sqlnet.ora file.

3) This highlighted line tell Network Services the location of the RADIUS Server.

4) The next step is to prepare the secure key that the Oracle server will use with the RADIUS Server. You must get a secret key from the RADIUS server that is exclusively for use in your database.

5) Modify the init.ora file for your Oracle database to include two new parameters.The highlighted parameter tells Oacle to not allow any automatic logins from the operating system.

6) The highlighted parameter shown here sets the prefix added to a user's name upon login to null.This means that the user's name is the same as the Oracle username

7) The next step is to tell the RADIUS Server about the Oracle database. The RADIUS Server see the Oracle server as a RADIUS client. The exact method of doing this varies depending on which vendor you use to implement the RADIUS server.

8) Now it is time to set up your user accounts. First, define the user to the database using standard SQl commands.

9) The final step is to set up the user accounts in RADIUS. The specific method depends, agin on the vendor's software.

10) Once you complete all these steps, any user or application that issues a CONNECT username/password command for the Oracle Server will be authenticated by the RADIUS software.
