I am using Google as an Identity Provider (IdP) to login to Moodle. I am using the SAML2 plugin.
The issue is that only user who already have an account in Moodle who can authenticate using SAML. If you used another Google account you'd get app_not_configured_for_user error although I've set the "Auto create user" option to "Yes".
Could any one provide shed some light on this issue?
