You don't say what OS you're dealing with here. Different OS's have
different gssd implementations which have a bearing on the issue.
If Linux is involved, you'll get more help mailing the linux-nfs
mailing list (linux-nfs.vger.kernel.org). If the server is Linux, a
patch has been submitted to work around this issue. That patch isn't
yet in a release. Contact me directly, or via the linux list above
for more info.
