Notes from sprint 3 retrospective meeting are at http://imageweb.zoo.ox.ac.uk/wiki/index.php/ADMIRAL_SprintReview_3. The summary position for this sprint is:
The general feeling is that forward progress is being made, but slower than hoped due mainly to unanticipated technical problems with integration of SSO authentication with file sharing services. We plan to push ahead with these issues only partially resolved in the hope that solutions will be found later. Meanwhile, some features will not benefit fully from SSO integration.
