Administrators sometimes delete the value of the GroupWise ID attribute (disassociate it) from an Identity Vault user and then re-associate (graft) it. This action resets the relationship between an Identity Vault user and a GroupWise account. This action only involves the GroupWise snap-ins and does not involve the driver. Care should be taken when using this procedure. Changes made to the Identity Vault user between the time the GroupWise ID is deleted and the user is re-associated are not synchronized to GroupWise. This is not a recommended procedure. Refer to the GroupWise Administration Guide for known issues and precautions.
