DHCP Server is not working in VLAN Steering environment

I'm running a PoC and have created an SSID on a solo AP-250, which will accept users and steer them to one of two VLANs based upon the AD group they are in. My AD/NPS/CA (Win2K12R2) is working correctly: the event log shows new logons being authenticated , and the incoming devices are steered to the right VLAN, but do not get an address. If I statically address the device, it all works, but that kinda defeats the object of mobility! That proves to me that the issue is with the AP not delivering DHCP leases.
I've configured DHCP servers for VLAN 20 and 30 on the single AP, on mgt0.2 and mgt0.3 respectively, and they are configured to respond to ping (but they don't). I've given them the right options and an appropriate scope, and they look fine. I've done this sort of thing thing on "non-VLAN-steering" setups and not had a problem, but something is not right here. I even completely deconfigured/reconfigured, to no avail.
The default VLAN for the SSID is 1, which is the management/native VLAN. I know this does not meet best practices, but this is a PoC, so its acceptably for the environment.
Any help would be great!

If you use Client Manager (or Wireshark if you prefer) can you see the DHCP requests and offers?

OK, sorry about the late reply...Aerohive DHCP *does* work...when I set it up correctly!
I'd set up the servers correctly, but not assigned them properly.

Thanks

Jim
