_check_password() is a private/internal API, so we make no guarantees about
it's stability. Instead, override the public authenticate() method with
something like this:

    def authenticate(self, user_id, password, domain_scope=None):
        if user_id in SPECIAL_LIST_OF_USERS:
           # compare against value from keystone.conf
           pass
        else:
            return super(CustomIdentityDriver, self).authenticate(user_id,
password, domain_scope)
