It means you need to apply the kernel patches which came with knfsd-981122 to
your kernel, specifically nullproc-2.1.1xx.diff.

Sun's automounter tries to find out what version of NFS the server supports by
sending a V3 NFS no-op operation, expecting either a "OK" or "Bad version"
response. Linux says "unauthenticated client", because all this happens before
the NFS authentication happens. The patch allows unauthenticated no-ops.
