autocomplete="off" on /admin/users/new

Created by: anthonyryan1

The form element rendered on /admin/users/new can be interpreted by a browser as a login form. By adding autocomplete="off" to the form element, it will disable this functionality in the affected browsers, saving people from clearing the fields before using that page, and improving UX.

I would attach a patch, but I'm afraid I'm not overly familiar with haml.
