DHCP local subnets zone director

I currently have two sites connected by a layer 3 network. At each site L3 switches route the traffic. At the main site i have a ZD setup and APs connected to the same layer 2 network ( Vlan 1 - management) - 192.168.5.X/24 - This is fine the Wireless client connect and obtain IPs in the Vlan 1 network.

At the second site we again have a Vlan (vlan 1 - 192.168.6.X/24) The APs have IPs assigned in this however the Wireless clients get IP addresses assigned from the management vlan at the other site. I need the clients to get IPs from the local DHCP scope not the 192.168.5.X scope.

Note Both sites have DHCP scopes setup on the lcoal L3 switches. Connecting a laptop to the ports get the correct IPs from DHCP. 

I found the following in the setup guide:

NOTE: All DNS, DHCP, ARP, and HTTP traffic from an unauthenticated wireless client will be passed onto ZoneDirector from the AP via the management VLAN. If the client belongs to a particular VLAN, ZoneDirector will add the corresponding VLAN tag before passing traffic to the corresponding wired network. After client authentication is performed, client traffic will directly go to the wired network from the AP, which will add the corresponding VLAN tag. This explains why it is necessary to configure tagged VLANs for all VLAN switch ports connecting to ZoneDirector and APs

I understand this but how can i achive this across the Layer 3 boundaries as both sites use the same VLAN IDs

I am going to do some testing in the next few days and i will report the findings. Thanks for the suggestions thus far.
