The superuser or tenant admin can disable a user. Disabling a user prevents that user from logging into the form server. If the user was had user has the role frevvo.designer (aka. was a designer user) the users' forms will become inaccessible to other users. Even if the forms were public users will get the error "This resource belongs to a disabled user".

In this case when the user tries to login they will get the error "Login is currently disabled".
