NAS conference talks on ACL interoperability

[Chuck Lever]

yesterday at the NAS Industry conference, there were several talks on 
ACL interoperability (see http://www.nasconf.com/ for presentation 
materials).

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.
