RADIUS Authentication

When RADIUS Authentication is enabled, end users will be considered enrolled and allowed to authenticate themselves by producing a valid RADIUS password and completing the RADIUS challenge, if configured.

What is the RADIUS challenge?

The RADIUS challenge comes into the picture when secondary authentication is configured in the RADIUS server in addition to the existing password-based authentication. Once it's configured, users need to provide the RADIUS password and a one-time passcode or secret key (according to admin configuration) for successful identity verification.

Prerequisite Steps:

Configure a RADIUS client in the RADIUS server for ADSelfService Plus using configuration steps specific to the RADIUS server.

For example, to configure a RADIUS client in freeRADIUS:

  1. Log in to the RADIUS server.
  2. Navigate to the clients.conf file (default location: /etc/raddb/clients.conf).
  3. Add the following snippet in the clients.conf file:
  4. client <xyz>
    {
    ipaddr = <xxx.xxx.xxx.xxx>
    secret = <abc>
    nastype = other
    }

    where,
    <xyz> refers to the ADSelfService Plus server name.
    <xxx.xxx.xxx.xxx> refers to the ADSelfService Plus server's IP address. and, <abc> refers to the secret key value created by the admin.

  5. Restart the RADIUS server.

Configure ADSelfService Plus for RADIUS:

  1. Navigate to Configuration → Self Service → Multi-Factor Authentication → Authenticators Setup.
