Hi Michael,

Could you try this patch: 
http://ndb1.internet2.edu/~aaron/initialize_backend_changes.patch . You’ll 
need to download it, and apply it by doing:

patch -d /usr/ndt -p2 -i /path/to/initialize_backend_changes.patch

This may fix that error message (assuming you’re not hitting the bizarre 
“class not found” error that others are encountering)

Cheers,
Aaron
