Yes I know. My idea was to export Posix 1003.1e draft 17 ACLs via NFSv4.
In that case, the mask entry is needed. I could apply the mask entry to
the other ACL entries, and not transmit the mask, but then retrieving and
setting the ACL over NFSv4 would result in the the loss of information.

Does Solaris export its Posix 1003.1e draft 15 (or so) ACLs via NFSv4, and
if so, can anybody tell me how it's done?

Thanks,
Andreas.
