We have a DECstation 5000/200 running Ultrix 4.1 and various Sun
workstations, some running SunOS 4.0.3 and some running SunOS 4.1.
When we try to NFS mount a DECstation partition on the Suns, the mount
works fine on the Suns running 4.0.3 and doesn't work on the Suns
running 4.1, failing with "Invalid client credential".  This partition
was previously served by a DECstation 3100 running Ultrix 3.1, which
worked fine with SunOS 4.1.  Due to circumstances beyond my control,
the partition had to be moved to the 5000 running Ultrix 4.1, and now
it doesn't work (and people are lining up at my door complaining!).
Of course, other Ultrix systems (v3.1, v4.x) can mount the partition.

I've checked all the obvious things: /etc/exports, /etc/netgroup,
/etc/hosts, rebuilt the YP maps, etc.  We're running mountd on the
DECstation without -i temporarily because of some unrelated (yes, I'm
sure) problems.  Has anyone else seen this?  Is there a fix available?
