Handling of unlinked accounts

If Account Linking is enabled without Automated Account Registration, users may attempt to log in via a provider on the login page even if no link between the accounts exist. If the "Redirect Upon Unlinked Provider Account" feature is enabled, this case is handled by redirecting the user to a configurable page. The default page informs users about the missing account link and guides them to the self-service page to create such a link after they have logged in with their local IAM account. For this, a login page is used where provider login options are temporarily disabled.
