I'm having trouble with getting the DuoPreauthAuthenticator working in the MFA logic code (mfa-authn-config.xml) for IdP 5.1.2. A use of it that worked fine in IdP 4.3. Just wondering if anyone already has a working example of using a PreAuth call in IdP 5.1? -- Michael A. Grady IAM Architect, Unicon, Inc.
