Comment 4 for bug 1116740

Sorry, I believe my previous comment was barking up the wrong tree. The problem is that a5b7fcf5f96a42bb4ac8110894b5cc146c552ad9 was committed to keystone before https://review.openstack.org/#/c/20127/ was merged into keystoneclient.

The commit related to this bug (a564b88e6) correctly reflects the fact that keystoneclient doesn't currently work with requests<1.1.
