819 * 1) ignore the already set proxyAuthz control
820 * 2) leave it in place, and don't set ours
822 * 4) reject the operation
824 * option (4) is very drastic
825 * option (3) will make the remote server reject
826 * the operation, thus being equivalent to (4)
827 * option (2) will likely break the idassert
828 * assumptions, so we cannot accept it;
829 * option (1) means that we are contradicting
830 * the client's reques.
832 * I think (4) is the only correct choice.
