Anaplan Connect 1.4 certificate authentication has changed from previous versions. New certs are issued by your company instead of Anaplan and to provide increased security, all certs must now be secured in a Java KeyStore. Because the KeyStore setup process requires a fair amount of setup this tool was created to simplify the process. Documentation included with the application as well as on this page covers complete setup procedures for Windows (if you want to set it up manually), a getting started guide that explains how the application works to include tips and a Final Steps guide that walks you through how to import your cert into Anaplan as well as your default web browser.
