The SID property gets the security identifier (SID) for a Windows user.
This property is read-only.
Syntax
HRESULT get_SID(
  [out]  DWORD **ppSID
);
Property value
Address of a pointer that on return points to the SID.
Error codes
This property method should return S_OK if the call is successful; otherwise, it should return an error code.
Remarks
Your implementation of IFWXAuthenticatedWindowsUser may return E_NOTIMPL for either the SID or Token property, but not both. It is not a requirement to support both properties, but one of the properties must have a meaningful implementation.
