When you create and configure a policy, it is important to understand that Storage Manager for eDirectory is now set up to provision and manage all new users that are created in the associated container.
If you have a network tool such as ConsoleOne or iManager creating home folders when a new user is added to the container or group associated with a policy, you need to remove the setting that creates the home folder.
You might also need to notify anyone who previously managed storage for those users that are now being managed by Storage Manager for eDirectory, to cease any manual storage management tasks such as home folder creation, renames, moves, etc., and let Storage Manager for eDirectory now manage the user storage.
