I am migrating our file share from Windows Server to Samba on Linux, and the only hurdle I have at the moment is the acl's.
Currently we have a number of directories that use the "Modify" permission on NTFS, so users can write to a directory, but once the file is written it cannot be modified.
On Linux, I had the idea that I would set an ACL for the directory to have read/write access, but have a default ACL associated with read only access. Is this possible? I'm not quite sure how to set a default ACL that differs from the parent directory.
