Securing file access by using file permissions

You can secure access by configuring file permissions on files and folders contained within the share through which SMB clients access data. File-level permissions are used in combination with share-level ACLs and, optionally, export policies to determine effective access rights. Files and folders might be secured with NTFS permissions or UNIX permissions.

If files and folders are secured with UNIX file permissions, then the mapped UNIX user and the UNIX user's groups are used to evaluate file permissions.
