Step 2: Add the Additional URL to Your DUO Setup

1. Log in to the DUO Admin Panel.
2. Go to the Applications section. 
3. Select your Generic SAML Service Provider application for Nitro. 
4. For each Reply URL, create two entries on ACS URL: 

  • One with the “?connection=<connection-name>” parameter (mark this as default to ensure it is used in IdP-initiated login scenarios (e.g., from Duo Central). 
  • One without the connection parameter.
