NameID Format is set to SAML_NAME_ID_FORMAT_EMAIL_ADDRESS, but Zitadel doesn't appear to be making use of the NameID provided by the IdP. When looking at the request, the SAML subject is provided as shown below. I would assume Zitadel would be able to match it to the user with the same email address?No external IdP found. I thought this could help with the auto-linking.
