Have you configured your Netware user as a library administrator to the library in question? Here’s a section from the Admin guide:
“…To administer one or more Applet Libraries, you must be assigned as the Library Administrator in the target libraries by the eDirectory administrator…The Applet Library object’s Library Administrators Page allows you to specify which users are authorized to create, edit and delete applets within the library. Use the Add and Remove buttons to add and remove users as Applet Library administrators, who must also be assigned to the FormativAdministrator Organizational Role.”
Please let me know if this doesn’t help.
