Configuring one SSID with Multiple VLANs

Tags: Cisco, Cisco, 4402 WLAN Controller, Wireless LAN controler
We have a schoolwide network with over 700 computers in multiple buildings.  We have a gigabit fiber backbone and appromiately 60 Cisco 3500XL switches and a 6500 series core switch tying it together..  We have installed about 40 1000 series access points in an attempt to create a mesh network using a Cisco 4404 controller.  The AP's appear on each of our 6 VLANs but we would like to have a single SSID across the campus.  We can only get the AP's on the same subnet as the controller to "come up"
1. Is this even possible?  
2. Could the problem lie in our port configuration to the controller?

HI lrmoore - I'm experiencing an issue with 3 1130 AG's each configured with 2 vlans and 2 ssid's, each ssid is associated with a vlan - I can only get an IP address when connected to 1 of the ssid's, the other one doesn't give me an address - I believe I have the asa 5505(the ap's are connected to the 5505) configured as you describe above with the ports trunked on all AP connections - It seems that something is amiss with one of the ssid's - Is what you described above basically all that needs to happen for this to work?

Thanks

ps I have a question opened concerning this also if the answer is more involved.

You must have a dhcp server for each subnet/vlan/ssid
