ZITADEL administrators can enable a setting called \"Ignoring unknown usernames\" which helps mitigate attacks that try to guess/enumerate usernames. If enabled, ZITADEL will show the password prompt even if the user doesn't exist and report \"Username or Password invalid\". While the setting was correctly respected during the login flow, the user's username was normalized leading to a disclosure of the user's existence.
