Problem

Your setup of SAML configuration may seem correct but still you may see a yellow warning icon beside the "Information required by your identity provider" area in the SAML setup page like shown here :

This is how you would replicate this issue

• 1. Verify a Domain
  2. Then setup the SAML configuration with your SAML Provider
  3. You then verify that from a SAML configuration angle - that the settings and configuration are indeed correct.
  4. Your users and you are also able to login/authenticate using the normal SAML flow. 
  5. However warning icon still appears

Cause

Developers have confirmed that this warning signal will not disappear as we have yet to confirm a mechanism to verify custom IDP configuration as they are a remote configuration.

Resolution

You can safely ignore the warning for now.
