Can't seem to get DHCPv6 addresses

I'm trying to use DHCPv6 to hand out addresses to clients on the LAN side of my router. I seem to have no problem with clients using ND/RA to generate their own addresses, but I never see any entries in DHCPv6. I was handing out /64's on the same range as the RA so I'm guessing that may be part of the problem, but I'm not sure how to overcome that? I tried handing out shorter addresses via DHCPv6 and that didn't seem to work. My current config is:

[tim@RouterDawg] /ipv6 address> print
Flags: X - disabled, I - invalid, D - dynamic, G - global, L - link-local

ADDRESS FROM-... INTERFACE ADV

0 DL fe80::4e5e:cff:fe9e:9912/64 Port 1 - WAN no
1 DL fe80::4e5e:cff:fe9e:991b/64 LAN Bridge no
2 G :1e0::2/64 Port 1 - WAN yes
3 G :1ef::1/64 LAN Bridge yes

[tim@RouterDawg] /ipv6 nd> print

managed-address-configuration=yes other-configuration=no

[tim@RouterDawg] /ipv6> dhcp-server
[tim@RouterDawg] /ipv6 dhcp-server> print

[tim@RouterDawg] /ipv6 pool> print
Flags: D - dynamic

NAME PREFIX PREFIX-LENGTH EXPIRES-AFTER

0 LAN2 :1ee::/64 64
1 LAN... :1ef::/64 64

Any ideas on how I might go about making this work? I use AT&T and they seem to be handing out a /61 or something like that, so I think I can carve out subnets if I had to, though I tried that (as you can see from the LAN2 pool) but still no dice.

I'm using OS X Yosemite to test. It's my laptop and one I'd like to use DHCPv6 on so I can hand off the same addresses as I want to add some IP-based security around iSCSI.

Any ideas?
