LOL sorry Jochen not meaning to nit-pick just hoping to point out that it reads the SAM database (which contains the info he was looking for) and is not going through the OU structures one by one.

Hopefully the discussion helps all of us to better understand what's going on. Probably only a few geeks on Earth fully understand the whole underlying schema, methodology of AD which leaves most of us to keep struggling with it here and there.

Cheers...
