I'll see what I can do with this tomorrow, but it can be difficult to deal with commits from an out-of-tree build, or even with commits that got merged in following other changes (which is what happened with this commit). I didn't see any obviously relevant commits in the git history, so I want to

I was hoping for some easy fixes :-P I created two system users, in both zones. Each user has different access and secret, but I copied the access and secret from the primary to the secondary. I can't imaging that this would cause the problem you're seeing, but it is something different from the
