State-Changed-Why: 

I have emailed the reporter, asking them if they can
test the patch:
  http://people.freebsd.org/~rmacklem/setattr-nfsuserd.patch
which I think fixes the reported problem.

It basically marks the "default" mappings to nobody for
cases where there isn't a valid name<->uid mapping and
doesn't allow Setattr to be done using those "default"
mappings.
