Comment: updated to Smart ID names

This article describes how to enable Nexus OTP in Smart ID Digital Access component (Hybrid Access Gateway) as two-factor authentication method for Cyberoam, to replace static passwords.

Nexus OTP can be either Nexus TruID Synchronized or Smart ID Mobile App (Personal Mobile) OTP, or any other OATH-based mobile OTP application, such as Google Authenticator or Microsoft Authenticator. 

With the setup described in this article, Nexus Hybrid Digital Access Gateway functions as a RADIUS server and Cyberoam as a RADIUS client. Nexus TruID is used as an example below and is available for iOS, Android, and Windows.

  3. The end user enters username, domain password and OTP.
  4. The domain credentials are validated by the Active Directory.
  5. The OTP authentication request is relayed to Hybrid to Digital Access Gateway Authentication Server via RADIUS.
  6. The authentication server validates the OTP with the associated TruID token and PIN from the user database.
