SAML Error - Could not validate SAML response

[satkum456]

when we click "Logout" button, we are getting the error message as "could not validate SAML Response". Also it says that logout happened successfully. I attached the saml properties and also SSO properties.

When the check box is checked for the property "Sign LogoutRequest. Set this property to true if the Identity Provider's SingleLogoutRequest service requires signed LogoutRequest.", it throws an error message as "could not validate SAML Response".

When the checkbox is not checked, it displays the error message as "An error occurred. Contact your administrator for more information.".

I attached the screenshot as well.

The "Could not validate SAML response" error in ServiceNow can occur due to several reasons. Here are some troubleshooting steps: 1. Check the SAML Response: Use a tool like SAML Tracer to capture the SAML response from the Identity Provider (IdP). Look for any errors or anomalies in the response. 2. Verify the IdP Configuration: Ensure that the IdP is configured correctly. The Entity ID, Single Sign-On URL, and Single Logout URL should match the settings in ServiceNow. 3. Check the Certificate: The certificate used by the IdP should be valid and correctly uploaded to ServiceNow. If the certificate has expired or is not correctly configured, it can cause validation errors. 4. Verify the User Information: The user information in the SAML response should match the user record in ServiceNow. If the user does not exist or the information does not match, it can cause validation errors. 5. Check the SAML Configuration in ServiceNow: Ensure that the SAML 2.0 plugin is activated and the SAML 2.0 configuration is correct. The Entity ID, Single Sign-On URL, and Single Logout URL should match the settings in the IdP. 6. Enable Debug Logging: Enable debug logging for SAML in ServiceNow to get more detailed error messages. This can help identify the exact cause of the error. 7. Contact ServiceNow Support: If you are unable to resolve the issue, contact ServiceNow support for further assistance. They can help troubleshoot the issue and provide a solution. Remember, always test changes in a non-production environment first before applying them to your production instance. nowKB.com
