I'm going to be just as unhelpful for the moment, but I can confirm 
something weird is going on with HUP and eap_tls.

Unfortunately I can replicate it on a server which is active, and can't on 
a test server ... most certainly restricts the ability for testing.

I've checked permissions a lot, believe me.
