Redmine

So, I'm using Redmine REST as a workflow backend for another project and all of a sudden, my simple calls are coming back 401.

Like, if you use this link:

[[http://www.redmine.org/projects.json]]

You'll see all the project (just one) on redmine.org whether you're logged in to redmine.org or not. It's just open.

But on my server, very suddenly, when you use the same projects.json link, if you're not logged in, you get a basic HTTP auth dialog. Which means I have to add that auth to all my REST calls where it wasn't previously necessary.

My suspicion is that the Ops guys changed the server somehow to create this situation, but I'm not sure what would do it. Anyone have any ideas?
