Is it possible to build classes on dhcp6.interface-id or dhcp6.remote-id?

Hey folks,

I'm trying to restrict access to a pool of addresses based on either the dhcp6 interface id or remote id (I've tried both, same outcome).

Here's a config snippet which can probably explain things a lot faster:

class "my_dhcp6" {
  match if option dhcp6.interface-id = "GOOD_DHCP6";
  log(info, option dhcp6.interface-id);

log(info, option dhcp6.remote-id);
# The path of the lease file
dhcpv6-lease-file-name "/srv/dhcpd6.leases";

shared-network  "network6" {
    subnet6 2607:fa40:fffd:0:0:0:0:0/64 {
    subnet6 2607:fa40:fffe::/48 {
        pool6 {
            allow members of "my_dhcp6";
            prefix6 2607:fa40:fffe:9100:: 2607:fa40:fffe:ffff:: /64;
            range6 2607:fa40:fffe:9000::/56;

When I do this, I get errors about no addresses being available.  As soon as I remove the allow_members statement from the pool, it works.  I'm doing this with DHCPD 4.3.5.

Is this functionality supported?
