EAP-TLS: Strategies for getting the right certificate to the right user

Thanks for all the thoughts. It's much appreciated to know that maybe it's
not just n00bness that is causing me to struggle with this!
I ended up making a pw protected page on my website (sigh)--but the limits
of that solution without internet access are pretty obvious I'd say!
And never mind that using TTLS-PAP with passwords saved as SSHA-512 doesn't
work on the iphone... !!! That's kinda insane if you ask me. But obviously
Getting certs on the iPhone has been a real hassle--it'd be easier with mac
or windows machines around because I could use iTunes, but anyway, it has
been done through the website option!
Now, I can't get EAP-TLS to work on my iPhone because I can't choose "mode"
EAP-TLS. Instead, it continually asks me for the username & pass, which is
precisely what I'm trying to avoid! I think there may be someway to signal
that my wifi prefers TLS mode that I don't know about.
If you have help on that point, that'd be great, and sigh&thanks!
PS Indeed my routher is not exactly hotspot 2.0 or captive portal compliant!
