What to do when the single sign-on gateway url is invalid?
I've implemented Single Sign On using ADFS as the Identity provider. We tested in sandbox, and again in production prior to release.
Now, in release we find that some users are able to login via SSO, while others using the same instructions are not.
Checking our login history, successful users login type is SAML SFDC Initiated SSO. Failing login attempts show 'Application' as the login type, and receive the error message:
'The Single Sign-On Gateway Url is invalid' What setting in Salesforce determines the login type and/or gateway url? How can I resolve this issue?
If the single sign-on gateway url is invalid- I'm not sure if you figured this out but we were experiencing a similar issue. 99% of our users logged in successfully and a couple received that same error. Our issue was case sensitivity of the user lookup. We're using ADFS which returns the user's email address after successful authentication which looks up the user's salesforce account using their federation id. What was confusing was their email address in AD looked fine (all lower case) but upon closer inspection we realised their O365 account wasn't syncing (mixed case).
Navigating to Setup > Single Sign-On Settings you'll find a setting labelled'Make Federation ID case insensitive'Once we enabled that setting, our users were able to successfully sign in. You can validate whether this is the issue by selecting the button SAML Assertion Validator on the Single Sign-On Settings page. You'll see something to the effect of 'unable to find the user' in results.

If you encounter an invalid Single Sign-On (SSO) gateway URL, it's essential to address the issue promptly to ensure smooth authentication and access to the services relying on SSO. Here's what you can do:
Check Configuration Settings: Review the configuration settings for your SSO solution. Ensure that the gateway URL specified matches the correct endpoint provided by your identity provider (IdP). Double-check for any typos or formatting errors in the URL.
Verify Connectivity: Ensure that the SSO gateway URL is accessible and reachable from your network. Use tools like ping or traceroute to verify connectivity to the URL. If there are network issues or restrictions, resolve them to ensure uninterrupted access.
Validate SSL Certificate: If the SSO gateway URL uses HTTPS, ensure that the SSL certificate is valid and not expired. Certificate issues can cause the URL to be perceived as invalid by clients. Update or renew the certificate if necessary.
Test the URL Manually: Try accessing the SSO gateway URL directly from a web browser or using a tool like cURL. This can help identify any errors or issues with the URL itself. If the URL is inaccessible or returns errors, investigate and resolve the underlying issues.
Review Error Messages: If you receive specific error messages indicating why the SSO gateway URL is considered invalid, pay attention to them. They may provide valuable clues about what went wrong and how to fix it.
Consult Documentation and Support: Refer to the documentation provided by your SSO solution provider for troubleshooting guidance specific to their platform. Additionally, reach out to their support team for assistance if you're unable to resolve the issue on your own.
Update Configuration: If you've identified the cause of the invalid SSO gateway URL (e.g., outdated configuration), update the configuration settings accordingly. Ensure that all relevant parameters, such as endpoint URLs and authentication settings, are correctly configured.
Test and Monitor: After making changes or updates, thoroughly test the SSO functionality to ensure that the gateway URL is now valid and authentication is working as expected. Monitor the system for any further issues or anomalies.
By following these steps, you can address the issue of an invalid SSO gateway URL and restore the functionality of your single sign-on solution effectively.
