Redmine User auth and Redmine Groups shared collections

Briefly:
Authorization is made if user is a Redmine user, activated and passwords matches.

Permission is the owner rights plus Redmine groups. What does this mean? Whenever a request like this is made /user/group/mycollection, if "group" is an active Redmine group and user belongs to that group then user can access mycollection.

WARNING
Collection directory is created in collections/groups/mycollection and symlinked to user directory at collections/user/mycollection

Storage > filesystem_folder setting at config MUST BE absolute (not ~/ or relative) This will be fixed soon.

I am testing right now and is planned to go to production, any suggestion or head up will be gladly taken.
