OEAP 600 cannot join WLC with auth-list enable

Question

I've got a strange problem here. In the office, my OEAP 600 can join WLC if there is no MAC authentication. When i enable MAC authentication at WLC, AP will fail to register. However, I try it at home and it works with both MAC authentication enable or disable. I suspect it is because of firewall in my office, but there shouldn't have any different in discovery and joining procedure for AP with MAC authentication enable or disable. I'm confused here. Please help.

Justin,
Below is error summary from WLC:
Last Error Summary
Last AP Message Decryption Failure----
Last AP Connection Failure     ---------      Timed out while waiting for ECHO repsonse from the AP
Last Error Occurred                ---------      Lwapp join request rejected
Last Error Occurred Reason    ---------      RADIUS authorization is pending for the AP
The error reason is probaly because I haven't added AP MAC address to ACS. With the same AP, at home using ADSL link, i have no problem.
Thanks.
