Thank you so much for your time. I truly did read the thread - many  
times (that's why my config worked perfectly once I changed the  
setting on the supplicant) and it was and is clear that you are an  
expert on the subject.... that's why I posted to this list.

Those of us who are new to these concepts could not become useful  
members of the community without your help.  You've made my week, and  
I hope that I can be helpful to someone in this regard in the future.

Kindest regards,
