Only the first of these should have -kau:

mi djuno le du'u da klama le zarci
There is some x1 such that I know that x1 goes to the store.

mi djuno ledu'u la djan. klama le zarci
I know that John goes to the store (which differs only in emphasis/focus
from "...that it was John who..."

mi na djuno le du'u la djan. klama le zarci
It is false that I know that John goes to the store
(contradictory negation: could be that I don't know who, it isn't
John, John goes somewhere else, etc.)
