SUMMARY: Pwd fails in directory mounted from VMS

I have received several responses already. They are unanimous. Everyone
says that the permissions on my mount point are bad. This didn't help, but
the problem is solved, I think.

I didn't mention in my first message that the mount was done by a link to
the magic /net directory:
ln -s /net/vmsmachine/directory /space/DIRNAME
Thus there was no actual mount point that I could mess with.

I got disgusted with the automounter, so I redid it in a more conventional way:
rm /space/DIRNAME
mkdir /space/DIRNAME
create an entry in /etc/vfstab:
  vmsmachine:DIRECTORY - /space/DIRNAME nfs - yes bg
mount /space/DIRNAME

(Note the uppercase DIRECTORY this time. It works this way, not the other.)

The problem is gone. I don't know why.

Thanks to Jim Davis, David Montgomery, Jeffrey Pyne, Nate Itkin, and Rasana Atreya.
