Back-end authentication describes the process of verifying user credentials with another system. It is used primarily to:
- Enable automatic management features, such as Dynamic User Registration (DUR) and authenticator self-assignment.
- Verify static passwords for users who do not have an authenticator and for Virtual Mobile Authenticator.
- Retrieve RADIUS attributes from a RADIUS server.
- Replace passwords to allow the user to log in with just a one-time password (OTP) in an environment where the Windows password is required (e.g. Outlook Web Access).
