Hi @thameera! Thank you for a quick reply!
I already tried changing issuer this way, but it was not working for me (I just double-checked). I tried it for google and okta. Google fails with app_not_configured_for_user (before redirecting to Auth0), which means saml:Issuer passed in SAML request doesn’t match Entity ID (configured in google workspace). Okta does redirect to Auth0, but then Auth0 replies/redirects with an error Audience is invalid. Configured: urn:auth0:TENANT_DOMAIN:CONNECTION_NAME .
EDIT worth mentioning that the request itself will succeed, but I think that’s only due to Auth0 ignoring unknown options (I tried some gibberish option names and the requests didn’t fail).
