Through a handy dandy `git bisect` command, I found that the commit that
caused this behavior is
https://github.com/apache/zeppelin/commit/57555f5ba16dd8109942513181d1330e9958744e.
Is this something that we might be able to get fixed before 0.6.1? Or am I
simply doing something wrong now that Shiro security has been added?
Thanks,
Jonathan
