Christopher,

For what it's worth, the connection string I use is:

   gltp:/vrf/home/warmerda/data/vpf/dnc13/h1316010

Within the h1316010 directory I have files in lower case:

warmerda at gdal64[105]% ls h1316010/
cat  dqy  env  hyd  lcr  libref  lineage.doc  obs  rel
cul  ecr  grt  iwy  lht  lim     nav          por  tileref

The driver is (I believe) case sensitive on linux/unix.  I can't
actually easily test this now as I don't have OGDI built into my development
build.

Best regards,
