1252 AP wont stay associated 5508 wlc

Question

Hi,
I have a newly configured 5508 and a test 1252 ap. The ap connects to the controller and then drops off repeatedly. I have pasted the errors that I am seeing on the ap below.

Thanks for the reply,
I have checked the time on the wlc and it is correct, it didnt have an ntp source but I have added one. The sw version is 6.0.199.0. I turned debugging on for the wlc and get the below output over and over again. There is no duplicate AP as this is the only one connected.
Many Thanks,
D
