We have a Mavericks server running Xsan. There are 7 users. We would like to give read and write permission to all but don't want to give permission to delete any file except for the Administrator. Is there any way to set this up..? Please help.
Set a custom ACL which does not include the delete and delete_child permissions. Of course, even without delete permission, if a user has write access to files, they can always overwrite files with other data. So if you're trying to protect data, this doesn't work perfectly.
