    // The problem why it cannot be done just now is that the SSL negotiation
    // with services.addons.mozilla.org fails very early - during an early
    // propfind, SSL returns X509_V_ERR_CERT_UNTRUSTED to neon, causing the
    // NE_SSL_UNTRUSTED being set in verify_callback in neon/src/ne_openssl.c
    //
    // This is not cleared anywhere during the init, and so later, even though
    // we have found the certificate, this triggers
    // NeonSession_CertificationNotify callback, that
    // causes that NE_SSL_UNTRUSTED is igored in cases when the condition
    //   if ( pSession->isDomainMatch(
    //      GetHostnamePart( xEECert.get()->getSubjectName() ) ) )
    // is true; but that is only when getSubjectName() actually returns a
    // wildcard, or the exact name.
    //
    // In the case of services.addons.mozilla.com, the certificate is for
    // versioncheck.addons.mozilla.com, but it also has
    //   X509v3 Subject Alternative Name:
    //       DNS:services.addons.mozilla.org, DNS:versioncheck-bg.addons.mozilla.org, DNS:pyrepo.addons.mozilla.org, DNS:versioncheck.addons.mozilla.org
    // So it is all valid; but the early X509_V_ERR_CERT_UNTRUSTED failure
    // described above just makes this being ignored.
    //
    // My suspicion is that this never actually worked, and the
    //   if ( pSession->isDomainMatch(
    //      GetHostnamePart( xEECert.get()->getSubjectName() ) ) )
    // works around the root cause that is there for years, and which makes it
    // work in most cases.  I guess that we initialize something wrongly or
    // too late; but I have already spent few hours debugging, and
    // give up for the moment - need to return to this at some stage.
