Although never ratified, POSIX ACLs are implemented in widely deployed operating systems. Existing attempts to map between NFSv4 and POSIX ACL models have been unsuccessful due to semantic incompatibilities. These new attributes allow servers to expose POSIX ACLs directly, avoiding lossy mapping.}, }
