Only one custom module is supported for an EPM System deployment. You can enable custom authentication for one or more user directories in the search order.
The custom authentication module must implement the public interface CSSCustomAuthenticationIF, defined in the com.hyperion.css package. This document assumes that you have a fully functional custom module that defines the logic for authenticating users against the user provider of your choice. After you develop and test a custom authentication module, you must implement it in EPM System environment.
