* missing the basic constraints extension. Of course
* there's a chicken and egg problem: we have to accept
* them here in order for them to be accepted later.
* Expired, locally installed certs are also allowed here,
* because we don't know (yet) what date will be checked
* for an item signed by one of these certs.
* Thus, accept certs with any of the allowed errors.
