Yeah, not useful at all. I'm going to raise a ticket with MS about
setting the identity when using EAP-TLS on Windows instead of
defaulting to 'host/<cert CN>' (with machine auth). We have to do
EAP-TTLS with EAP-TLS inner just because of this limitation.

I'll ask them about their session resumption plans with TLS1.3 at the same time.

Cheers
