i unfortunately don't have admin access, so i can't test this out. The docs ("soap.txt") do not in any way specify that the request requires admin privileges, so i have been testing it with my account (which cannot work, it turns out). i have requested an admin-capable account with which to develop the app, so i'll need to wait until then. As soon as i've got the access, i'll try your suggestion.
My ZCS version is listed in the top post of this thread: 7.1.1.
