Hi! Anyone have an idea why am i getting 

Error: app_not_configured_for_user

 from google SSO? Was following this instructuions Getting this error for any user: existing/non-existing, with/without SSO enabled

SSO only works if the email in the saml assertion is already created as a user in Fleet. In other words Fleet does not yet support just in time provisioning. You mentioned the user existing already so other than that it's typically configuration issue. Can you double check that the entity ids are the same between Fleet and the IDP?

It was actually middleware issue. 😬 Fixed it!
