Please provide more information e.g:

What software version is running on the WLC?

What is providing DHCP, and what is the scope?

Have you tried any debugs on the controller to see any LWAPP join requests, reaching the controller.

You mention above the part number for a autonomous AP then state it is LWAPP. Was it converted? If it was, is it attaching to the same controller it was initially attached with in the conversion process? If not, the SSC is the issue. You must install the SSC hash on the controller. Next, look at the date and time on the controller to insure accuracy. Next is the AP getting an IP address on the same subnet as the controller management and AP manager interface? If not then insure you get an IP address and enable option 43 or DNS lookup of the controller.
