Once you've retrieved the IdP Entity ID, the Metadata URL and the Entity ID from your provider (see the list of providers for specific details), the configuration on Clario is pretty simple.
Log in into Clario as an administrator > Extra > Settings
Navigate to SSO settings
Enable SSO
Select the OpenID Connect provider
Enter the Client ID
Enter the Client secret
Enter the Server URL
And that's it! Don't forget to click the 'Save' button
You should now be able to see the Login with SSO button
Be aware that the user needs to be created on Clario to be authenticated with SSO.
