This will ensure the ACL applied to the share is inherited by child files & subdirectories. To allow our users to add to each others directories we simply add the file_inherit & directory_inherit attributes to an ACE. Without the sticky bit set, any user with write and execute permissions for the directory can rename or delete contained files, regardless. The ACEs in an ACL are evaluated from top to bottom until an ACE that applies to the user is found, once a match is found all remaining entries are ignored, making the order of ACEs paramount. 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.

Understanding File & Directory Permissions Correctly configuring directory permissions is the solution covered in today's blog post. This means if one user creates a new directory in a share, other users are able to view the new directory, but are unable to add anything to it. Creating a network share on macOS does not automatically propagate assigned permissions to child files & subdirectories.
