05-21-2019-13.54.04.287 SecureAuthAdapter.ValidateProofData - Pin does not match sent OTP, returning false

Cause: Using the API realm for multiple purposes causes this issue. You cannot use a realm that is setup for Login for Endpoints. Nor can you use a realm that is setup with the "Validate OTP" Endpoint.

Resolution:

In order to fix this issue, please perform the following

1. Pick or create a realm that only the ADFS VAM will connect to.

2. In this realm, open the Web.config editor and search for OTPFieldMapping. If it exists, remove it.

3. On the API tab, make sure Login for Endpoints is not enabled.
