When you use Group Operations and want to save the groups that you have created, OES Remote Manager requires you to save the file on the server locally or assign it to an eDirectory object.
Before you can save it to an eDirectory object, you must extend the eDirectory schema to access the attributes for OES Remote Manager group operations at least once in the eDirectory tree that you are saving to.
You can do this easily by clicking either the Extend eDirectory Schema for Group Operations link on the OES Remote Manager Configuration Options page any time before you create a group or the link in the failure error message displayed when saving the group. As with all schema extensions, you must have the necessary rights to extend the schema.
The message NDS schema extension complete is displayed on this page when the operation is done. Then you can save the group.
