Hi again Alex
At the risk of being a pest, is there any more news on this?
Otherwise, I may be 'driven' from SharePoint 'into the arms of' Alfresco, KnowledgeTree or ownCloud as a Moodle 2 repository :-(
The generic Moodle 2 WebDAV repository interface/file-picker works (with a little tweaking) with any of these, as does the dedicated repository interface/file-picker for Alfresco. They all also have AD/LDAP authenticationcation. So, can sit, reasonably comfortably, in a Microsoft environment.
I do appreciate that development may be somewhat challenging. The Moodle 2 file/repository system is somewhat idiosyncratic (and has caused some angst in the Moodle community) and is likely to be refactored for Moodle 2.3. Suspect managing fle/folder access rights between SharePoint and Moodle 2 may be a particular issue.
Appreciative of your efforts.
Geoff
