Works with CiviCRM 4.7 and should work on CiviCRM 5.0 or higher
When an anonymous visitor fills profiles and other forms having email address and employer fields, this extension searches for an individual with a matching email address and populates the form with his or her employer. This requires granting the "access AJAX API" permission to anonymous users.
This is meant to address problems in CRM-10128 (leaving the employer blank on a profile will unset your current employer if you have one) and problems of people typing organization names different ways.
