we have a macpro machine which we use for data storage. The admin user is 'alain' but there are several other users (like 'stevenbeel') that can administrate (in group 'admins') the computer by smb (add/delete/modify folders and files in Finder).
When we create a new folder as one user (e.g. 'stevenbeel') then we do not have permissions to write or edit files in it as another admin user except for that user 'alain'.
(in attachment a screenshot of a directory (directory 'zero2') in which some admin users cannot write. You'll see at the end of the permissions there is a '+'. When that '+' is there, all admin users have all permssions to the directory.
How can other admin users create folders that immediately have all permissions set for all admin users?
