The RADIUS Username Password Credential Validator verifies credentials using the RADIUS protocol.
RADIUS supports strong authentication with both one-step (a combination of regular password and a one-time password in one field) and two-step (challenge-response) authentication. Two-step authentication is supported in the HTML Form Adapter.
Important:
If your RADIUS server is a Microsoft Network Policy Server (NPS), passwords containing special characters will not be encoded and decoded properly due to limitations with NPS.
Tip:
RADIUS server messages are used by the HTML Form Adapter to determine the two-step authentication scenarios and to present a sign on window to the end users.
