The file server or file system does not supply the information you
want defaulted.  Each user supplies the modification mask for a new
file or directory.

A user can set a default for the modification mask on his files and
directories, though.  This is called the umask.  This command will set
the umask for the current process (shell) to the default you want:

    umask 002

You could request users to set this in their login scripts or you
could even set it for them by modifying /etc/profile and/or other
files run by various shells.

But, in the end, the user controls this.
