MCX in Casper

Contributor III

We are thinking of ditching OD and moving to Casper for enforcing MCX, so I
have been playing around with that this morning.
Are you supposed to be able to upload any plist via "Upload Setting"? I can
find no documentation on this feature. Anytime I click "Upload Selected
Template..." on the next page I get an upload failed error.

Is this looking for something in a special format/extension or is there
something wrong with my JSS :s?
