Configuring RADIUS Authentication App¶

Below are the steps for configuring Splunk to use the RADIUS authentication app with a RADIUS server.

Configure Your RADIUS Server¶

Before you configure Splunk, you'll need to setup your RADIUS server per the vendor's documentation. Below are some links to information on how to setup some vendors:

• Microsoft IAS
• Cisco ISE

The RADIUS authentication app will load roles from the RADIUS server if you set up an attribute containing a comma or colon list of roles. You'll need to configure the RADIUS authentication app to tell it which attribute it ought to us to find the roles. See Configuring_Roles for more information.

Configure The RADIUS Authentication Splunk App (using the setup screen)¶

You'll need the following information from your RADIUS server in order to configure Splunk:

1. Shared secret
2. RADIUS server address
3. (optional) username and password of a valid account (so that you can verify the configuration before you save the settings)
4. (optional) the vendor code and attribute ID if loading roles from the RADIUS server

Below are the steps to setup the app:

1. Install the RADIUS Authentication app
2. Open the setup app and configure the RADIUS authentication app (go to Manager » Apps » click "Set up" for the app "RADIUS Authentication"
3. Enter your RADIUS server settings and save the settings. Enter a sample user account in order to verify the configuration. The setup screen will not persist the settings if the test user account fails (which prevents saving a configuration that does not work).
4. Logout and test the configuration by logging into Splunk. Make sure to use an account that does not exist on the local Splunk install (accounts on the local Splunk install will still authenticate locally and thus will not test the RADIUS server configuration).

Configure The RADIUS Authentication Splunk App (manually)¶

The radius auth script can be configured manually by editing the file $SPLUNK_HOME/etc/system/local/authentication.conf with the following:

[radius_auth_script]
scriptPath = "$SPLUNK_HOME/bin/python" "$SPLUNK_HOME/etc/apps/radius_auth/bin/radius_auth.py" 
scriptSearchFilters = 0

[authentication]
authType = Scripted
authSettings = radius_auth_script
