hIdentKey
Handle of the identity key object required to proof the internally created temporary key.
hNewPolicy
Handle of the policy object providing the new authorization data.

TSS_E_INVALID_HANDLE - Either hObjectToChange, hParentObject, or hIdentKey is an invalid handle.
TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
