Configuring local identity fields determines which fields will be displayed as input controls on the user registration and profile management pages.
When registration is enabled for a local identity profile, select a local identity field to be the unique identifier for the purpose of identifying the users. To enable email ownership verification, add a field to store the email address and another field to store the verification status. While the former can be any field that uses the Email or Text input control, the latter must use the Hidden input control.
