Yes, this works fine in my tests.

I have used certificates generated by Microsoft CA with IAS and that has
worked fine. Are you sure you configured the correct CA certificate to
wpa_supplicant? Have you tested whether this works without ca_cert
configured in wpa_supplicant.conf?

Well, yes, but getting this configured is going to be quite complex. One
would need to add all the required certificate extensions and then load
the certificate. I have seen it done once, but I would not be doing it
without plenty of time available to waste on this.. ;-)
