The Solution:
The local mount point directory was set to 700; I couldn't see this
because it was hidden by the mounted filesystem, whose perms were 755.
Once the FS was umounted, the perms on the local mount point dir changed
to 755 and re-mounted, the problem was fixed.

Thanks to all... I gave up on the problem after fighting with it for
several hours around 6 am. By the time I woke up at 11 am, I read my mail
and had the problem fixed in 10 minutes. Great people around here...
