I've been told that I can configure iPhones in our enterprise to authenticate to exchange/activesync with certificates (so as to not require a user to enter their username/password) but I can't seem to find any good guide on doing this. We currently have about 30 iPhone users who we simply manually configure Exchange with and instruct them to change their password on the iPhone when they change their windows password, but this is obviously an administrative headache (users lock their accounts when they forget). I understand there's an iPhone Configuration utility but really, I don't know where to begin. I've tried searching to no avail. Can someone point me to a guide or in the right direction? Thanks in advance..
