[From krb5.conf]

You should put the KDC certificate paths in "pkinit_identity", and the
client certificate paths in "pkinit_identities".  (These are two of the
most confusingly named variables in krb5.conf, and we are considering
introducing new names for them and deprecating the old ones.)

Since the KDC isn't seeing a "pkinit_identity" configured, it isn't
offering PKINIT.

If you haven't read it already, see:
