I'm testing a pair of 5760s for a near-term production rollout. I have the dot1x employee wlan working, but am having trouble with the guest web-auth wlan. We have a foreign controller with connected APs and an anchor controller in the DMZ. We're using an external redirect to the ISE guest portal. ISE is working with our production equipment and hasn't been changed. However, I'm not able to get an IP address assignment to test the ISE redirect. When I remove all of the web-auth configuration, I'm getting an IP address without issues. My configuration is attached below, and would appreciate an extra set of eyes.

Have you tried this by enabling DHCP snooping for the vlan 330 on your 5760 & trust 5760 uplink ? In the below I have assume 10G port of 5760 is map to a etherchannel (Po1). Otherwise trust the physical interface.
ip dhcp snooping
ip dhcp snooping vlan 330
!
interface Port-channel x
switchport trunk native vlan x
switchport trunk allowed vlan x,y,z
switchport mode trunk
ip dhcp snooping trust

I haven't. I had DHCP snooping on the foreign controller for non-anchored WLANs, but was often not getting DHCP addresses, even though the config was right as far as the documentation was concerned. So I pulled it off and started getting addresses.
Is there something missing or wrong in the above config? I haven't imported a certificate yet, as I was going to work that piece once I had an IP address and could perform a redirect. Is which cert you are using specified as a trustpoint in the non-global parameter-map?

In my production 5760/3850 guest access set up, I have enabled DHCP snooping & things working fine. I am running 3.6E code & Clearpass is the guest portal & not ISE.
Regarding certification, this is what I have done

Hi,
You are using web-auth..So ip address should be with out any authentciation. Only thing coming in between is the Mobility tunnel to pick the ip address from Anchor controller. Is one of the 5760 Foreign and the other one Anchor ?
Verify Mobilty tunnel:
> sh wireless mobility summary
>show wireless client mac-address <MAC ADDR> detail
> sh ip device tracking mac <mac-address>
> debug mobility handoff..on Anchor
