I have some difficult problem with Linux permissions - I use Ubuntu 16.04 LTS. I have there an admin account (not root) and I have created there directory which is available for all users in path /home/sadmin/ftp/freeForAll with chmod's 777. Of course when any user logins to his own ftp account he can put there files and remove them without any problem like it should be. But problem begins when any user will create there some directory. This specific directory can't be removed by anyone except this particular user, who has created it. Is it possible to set, in some way, inheriting of permissions of parent directory freeForAll --> "/home/sadmin/ftp/freeForAll" for all newly created subdirectories/nested directories and files?
