Yes, well - the point is rather that the Dead at Dunharrow have nothing to do with Sauron - they are undead merely because they are oath-breakers. And the Ringwraith, that's again a different mechanism: they "faded", they are not, in fact, undead in the typical sense of the word. They are in the wraith-world, but they are not subject to Sauron's control because of any necromancy, but because of the simple magic of the Rings - ALL Rings, based on their magical nature, and not any necromancy:

I guess Morgul could be one example of a Necromancy-soaked place, though.
