We are trying to implement quotas on CIFS shares presented via NAS. The quota options are for users and groups but the groups are UNIX groups, not Windows. This basically limits us to using user quotas. We can set the quota user to be a domain group name and as long as the files are owned by the group it works. By default, ownership for files created on the share are set to the creator. We know how to change ownership of the files to the group name but that is not manageable. Is there a way to set the default ownership to the group name for all new files added to the share for a CIFS share?
