You don’t need the LDAP Server if you are using the Novell Client on the workstation where you are running Formativ Runtime and your applet solution. Formativ Runtime should leverage the Novell Client authentication to access eDirectory and discover the config object, which in turn, should show you the associated Applet Libraries. As you may be aware, you will need to be logged into eDirectory as the appropriate user etc.
Most times the cause will come down to a rights issue or another configuration problem.
If you cannot resolve the problem, for each workstation with the eDirectory access issues, can you send the Formativ Configuration information to email@example.com.
You can obtain the configuration by selecting Help | About Formativ… from the GroupWise main menu. When the About Formativ dialog appears, go to the Configuration tab and click the button Copy to clipboard. Then paste the text into your reply email (or save it to a plain-text file and include it as an attachment).
