Hi Rich,

Well, I looked and didn't find a .grassrc5 file in my server
environment. According to the libgrass README the MapServer-GRASS
interface will read information about Location, Mapset and Database from
$DOCUMENT_ROOT/.grassrc5. I would have thought that this was only done
with relative pathnames, as in the standalone GDAL utilities, but
perhaps it also happens with full pathnames. In that case it is a bug.
You could try to remove .grassrc in $DOCUMENT_ROOT, and see if you can
access GRASS rasters with with their full path in MapServer. I have been
doing it for years!
