This was just plain vanilla user folder. I also get it with ZClass
instances, though I get a reauthentication request (impossible one) in that
case. In  2.1.6, I'd get reauthentication requests for both external
methods and ZClass instances.

I don't see how to accomplish this in my page. The root folder isn't
owned by anyone, and I can't change it to be owned, I think. The
external methods are all owned by my manager user, can I can't seem
to change that either.

If it is indeed the same problem, it seems to be a Zope core bug.

In fact I misreported that moving the external method to a subfolder
solved all problems -- it still fails (at least in 2.2.2, perhaps it worked
in 2.1.6), as long as the local role needed to execute it is added to the
user in a subfolder below it). If the role is added in the same folder or
a folder above the definition of the external method, it works.
