I successfully added an enterprise connection with Azure AD. It is working. But on the login screen there is now a email field, which I don’t want. It has something to do with the enterprise connection. How can I hide or disable it?
From the screenshot you provided, it looks like you have Identifier First enabled as the Authentication Profile setting for New Universal Login. With this setting enabled, the email field will still appear on the login page even if there is no Database connection enabled for the application.
