I've installed an owncloud server to share it with 7 others people. I have set a symbolic link from their data folder to their home (/var/www/owncloud/data/$USER -> /home/$USER/owncloud ). So every user needs to have the rights to write into a www-data folder, but if I add the users into the www-data group, they will be able to see documents from each others. I want every user's folder to be private but www-data must have read/write permissions. How can I do that?
Thanks for your help.
