My guess is that the mount point has the wrong permissions.  Unmount the
file system and check the permissions on the mount directory.  You will
probably want to make it 0755.

I had this problem on an ATT 3B15 running SysV 2.1.2.  The mount point had
permission 000 (I don't know how it got set to that -- I didn't do it!).
When I was root everything was happy.  When I wasn't root things like pwd
and ls -d . (where . was the root of the filesystem) failed.

I just checked this on a VAX 11/780 running 4.3BSD.  The problem is there,
too.

It seems odd that the permissions of the mount point affect access to the
mounted file system.  Is this a bug or feature?
