We're at the bottom of the learning curve w.r.t EAP-TLS but on the way
to the fish and chip shop this lunchtime did come to the same
conclusion that perhaps I was getting over concerned as to what to do
in the event of the OCSP server failing. As you said, can't imaging
we'll be revoking millions of certificates when we start rolling them
out there.
Think perhaps I'll use the softfail ... :-))
