If you want to use the Active Directory driver to modify objects in an AD LDS application directory partition, you must ensure you set the Default Naming Context for the LDS instance to point to the partition. If you do not correctly configure the Default Naming Context, when the driver attempts to modify an object in an application directory partition, the operation fails with an LDAP_UNWILLING_TO_PERFORM error.
For more information about configuring the Default Naming Context for an AD LDS instance, see Setting the Default Naming Context for Your AD LDS/ADAM Instance.
