Retool now enables you to test your custom single sign-on integration with the click of a button. When you click the Test Connection button on the Single Sign-On (SSO) > Custom SSO settings page, Retool checks that the proper groups are mapped, the right user metadata is sent from your identity provider, and the integration works seamlessly. Testing this connection does not change the current user's permission groups, and you won't be locked out if SSO is misconfigured.
This feature is generally available on Retool Cloud and on Retool Self-hosted versions 3.93 and later.
