matching class to pool

[Adam Moffett]

Hello,

I have a wireless AP that inserts option82 circuit-id and remote-id into 
DHCP requests.  What I'm trying to do is use a different pool for hosts 
connected to that AP.  Based on what I read in the man pages and some 
examples on the web I thought this would work, but it's clearly not 
working so I'm wondering what I did wrong.

If I uncomment "allow unknown-clients" in the pool then wireless clients 
start getting IPs, and the circuit-id in their lease matches what I have 
in the config here (which is just the MAC of the AP as you can see).  If 
I comment the "allow unknown-clients" then dhcpd says "DHCPDISCOVER from 
00:c0:9f:d1:1b:09 via 192.168.1.55: network Wireless: no free leases"

Can anyone enlighten me?  Thanks.
