Compatibility between NFSv4 ACLs and Windows (NTFS) ACLs

NFSv4 ACLs are different from Windows file-level ACLs (NTFS ACLs), but Data ONTAP can map NFSv4 ACLs to Windows ACLs for viewing on Windows platforms.

Permissions displayed to NFS clients for files that have Windows ACLs are "display" permissions, and the permissions used for checking file access are those of the Windows ACL.

Note: Data ONTAP does not support POSIX ACLs.
