Machine auth fails but user auth works

[Alan Buxey]

Machine Auth client appears to be using the wrong CA. 

Your proxy.conf doesn't look to good either, surprised eduroamUS haven't contacted you as you'll be sending loads of invalid junk upstream for no purpose.  Should use unlang to check realm is valid and then update control proxy-to-realm to eg 'eduroam' and define eduroam target in proxy.conf
