When a dropbox is viewed by an instructor, the student folders are exposed as ids rather than eids, e.g.:
where 6778fba8-9df2-474b-006e-7984ed1fbeae is the id of student with eid "smstudent".
This makes WebDAV access to the dropbox less useful for instructors, as it's impossible to associate the folders with individual students. It's also inconsistent with the rest of Sakai, as we're not exposing the id to end-users anywhere else.
