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

[Chevalier Violet]

Update: I got my iPhone working. I think the problem was that I needed to
import the client.p12 cert (helpfully mentioned not very often of course).
Anyway, it's working!

As for how to make THAT relatively automatic... wow, I may need the website
Alan proposed.

Best,
David
