// This test tests two specific items:
// 1. Are name constraints properly enforced across the entire constructed
// certificate chain? This makes use of a certificate hierarchy like so:
//  - (trusted) root CA with permitted subtree dNSName example.com
//  - intermediate CA with permitted subtree dNSName example.org
//    a. end-entity with dNSNames example.com and example.org
//       (the first entry is allowed by the root but not by the intermediate,
//        and the second entry is allowed by the intermediate but not by the
//        root)
//    b. end-entity with dNSName example.com (not allowed by the intermediate)
//    c. end-entity with dNSName examle.org (not allowed by the root)
//    d. end-entity with dNSName example.test (not allowed by either)
//  All of these cases should fail to verify with the error that the
//  end-entity is not in the name space permitted by the hierarchy.
//
// 2. Are externally-imposed name constraints properly enforced? This makes use
// of a certificate hierarchy rooted by a certificate with the same DN as an
// existing hierarchy that has externally-imposed name constraints (DCISS).
