Discovered an ID10T error in my SSH_CLIENT string.  It did not get set and
therefore the rules with it in did not work.

I even missed this when I went through all the errors that occured, I did at
least pick up one mistake myself in that pass through.

Thank you for steering me back to the culprit.
