( СРОЧНО )Как изменить разрешения и доступ к общему сетевому ресурсу Samba, размещенному на CentOS7?

Проблема, похоже, заключается в липкой части /tmp.

$ ls -ld /tmp
drwxrwxrwt⃝   1 root  root  1044 Mar 13 12:09 /tmp

https://en.wikipedia.org/wiki/Sticky_bit

When a directory's sticky bit is set, the filesystem treats the files in such directories in a special way so only the file's owner, the directory's owner, or root user can rename or delete the file. Without the sticky bit set, any user with write and execute permissions for the directory can rename or delete contained files, regardless of the file's owner. Typically this is set on the /tmp directory to prevent ordinary users from deleting or moving other users' files.
