Are the AP and WLC in same subnet ?

If not then did you configure a method to register an AP to WLC . Example:Option 43

Also try Static config on AP:

#capwap ap ip address <IP> <MASK>
#capwap ap ip default-gateway <GATEWAY>
#capwap ap controller ip <WLC-IP ADD>

#capwap  ap  primary-base  10.100.82.10
