Title:
  Attaching a volume to a VM generates authentication error

Status in OpenStack Compute (nova):
  Expired

Bug description:
  Description
  ===========
  When I try to attach a volume to a VM, the operation fails. From the nova logs I can see first that an authentication fails and then an "Unexpected API Error".
  This happens with the "nova volume-attach" command.

  The "nova volume-attachments" command works correctly.

  This happens regardless of the user I use, even with a user that has
  the admin role.

  Steps to reproduce
  ==================
  $ nova --debug volume-attach cb22727f-32f8-49e9-8136-5395882d259a 2fe6c45f-cce9-43ea-90ac-ff0d574121b0
