Small patch for bloodhound-python ce to test resolved IP before choosing blindly

domain.py

        import ldap3
        
        # Convert the hostname to an IP, this prevents ldap3 from doing it
        # which doesn't use our custom nameservers
        q = self.ad.dnsresolver.query(self.hostname, tcp=self.ad.dns_tcp)
        for r in q:
            try:
                logging.info('Testing resolved hostname connectivity %s' % r.address)
                _tmp_serv = ldap3.Server(r.address, connect_timeout=5)
                _conn = ldap3.Connection(_tmp_serv)
                _bind = _conn.bind()
            except ldap3.core.exceptions.LDAPSocketOpenError:
                continue
            else:
                if _conn:
                    ip = r.address
                    break
