Dumbledore does not talk about what he knows, unless the listeners
have a need to know. It was, for example, clear that he could see
through Harry's Invisibility Cloak, but  didn't tell Harry he actually
knew until it was necessary to do so, and he certainly never let
Professor Snape, a man he clearly trusted, know about it.

Carol responds:
Are you sure about that? Snape found the Invisibility Cloak outside
the Whomping Willow in PoA and knew that it was Harry's. How would he
know about it unless DD told him? Granted, he may have known about
James having it during their school days, but that wouldn't
necessarily mean he would know that Harry has it now unless DD shared
that information with him. He may have known (or suspected) that Harry
had it as early as SS/PS, when he knows that a student (almost
certainly Harry since so few kids are staying at school over
Christmas) is in the restricted section of the library. (I have the
movie version of the scene in my mind, though, so I could be mistaken
on this point.)

Carol, curious as to what you mean by "as his name certainly implies"
