Address issues w/ ChefJig connection info [2/2]

This intermediate pull addresses Chef connection items that were found
and corrected while testing the Chef Jig.

There some intermediate debug comments that have been left in and will
be removed in follow-up pulls. 

I choose to bring this in more quickly because it was blocking others.
