Running a Sky Factory 4.2.2 server.

Ender Utiltiies barrels are able to be clicked by anyone. Although it says "you don't have permission", the items will drop out of the barrel anyway.

The block is claimed (island claim) and everything.

Which mod handles the claim stuff, and how does that work normally? I think this might be because I use a click event handler on the barrels, maybe it has a higher priority than the claim mod's handler so it gets handled first...

So I would need to know the mod that handles the claims so that I can test against it. (I'm not downloading an entire huge mod pack and launching that every time to test changes...)
