Funny part is, that NFSv4 supports SIDs for user authentication, but the Linux implementation leaves it out (among all the other ACL features) simply on the basis that Linux doesn't support them at all.
The FreeBSD, Solaris, Mac OS X, and Windows (yes, even Windows) implementations of NFSv4 are fully featured with this stuff.
I really wanted NFSv4 ACLs but Linux doesn't like it while FreeBSD doesn't make use of my hardware (intel p/e cores) in the most efficient way.
