Hi Law,
In theory, that should work. However, we would need to know more details to understand what you might be running into. You mentioned that "RADIUS" WLAN works with same AAA server but "OFFICE" does not. Can you try a simple test (assuming this is in the lab), where you delete the "RADIUS" WLAN and try only the "OFFICE"? It would be interesting to see the result. Also, can you let us know the version of ZoneDirector and AP?
