NFSv4 ACL interoperability has issues in three categories: 1. NFSv4 ACLs mapped to and from POSIX mode bits 2. NFSv4 ACLs mapped to and from POSIX-draft ACLs 3. NFSv4 ACLs mapped to and from NTFS/CIFS ACLs it turns out that NFSv4 ACLs can't map cleanly to any of these other access control paradigms, but there is work on standardizing the mapping semantics. one of the presentations was given by the team that just posted the recent IETF draft on NFSv4 ACL mapping. --------------010301040600080106090008--
