Cause 1: The certificate is incorrect


Manually retrieve the Signing Certificate from the ADFS Server:

  1. In Windows, click Start > Administration > ADFS 2.0 Management.
    The ADFS 2.0 Management dialog box is displayed.

  2. Select Trust Relationship > Relying Party Trusts in the left-hand pane.

  3. Right-click on Relying Party Trust, and select Properties.

  4. Click on the Signature tab.

  5. Click on the name of the Signing Certificate, and click View.

  6. Click Copy to File…, and select Next.

  7. Select Base-64 encoded x.509 (CER), and click Next.

  8. Specify the file name, and click Next.

  9. Click Finish.

  10. In Adobe Workfront, navigate to Setup > System > Single Sign-On (SSO) and manually upload the Signing Certificate.

Cause 2: The certificate is signed using DSA when Workfront is expecting an RSA signature


Recreate the certificate and use the RSA signature instead of the DSA.

Cause 3: XML Data is incorrect


Re-export and re-import the XML metadata from the ADFS management system.

Cause 4: The request could not be performed due to an error on the SAML side
