I've been searching a way to change default SMB share setting to enable newly created share to have following properties:

• All users added to the SMB have read-write capabilities as no-root users
• All users added will be able to read and modify other users' file within the SMB

Such properties are meant for collaboration purpose when implemented. Until now, we do that by manually updating the permission to the SMB and giving certain user Group a full control on the SMB.

The manual suggest changing the File Create Mode/Mask but still no luck after changing those configuration. Am I missing something?
