SSO Troubleshooting: The Status Code Of The Response Was Not Success (Responder)
Learn how to resolve an AD FS relying party configuration error during SSO
What This Error Means
During single sign‑on, a learner successfully authenticates with their identity provider but sees the following error after returning to Foundry:
The status code of the Response was not Success, was Responder
This error most commonly occurs when Microsoft Active Directory Federation Services (AD FS) is used as the identity provider.
Why This Happens
This error indicates a configuration issue in the AD FS relying party trust for Foundry.
Specifically, AD FS is unable to validate the SAML response because the required Foundry signing certificate is missing or not correctly configured.
How to Resolve the Issue
- Open AD FS Management
- Locate the relying party trust for Foundry
- Open the trust properties
- Go to the Signature tab
- Confirm that the Foundry signing certificate is uploaded
- Save the changes
After updating the relying party trust, retry the SSO login.
