This Wlc controller is configured with 11 WLANS (just only one broadcasting its ssid?. Each WLAN is attached to its interface. Finally the port is connected to a trunk port.
We have some problems with the clients that try to associate to the hidden ssid. Thay cannot. But if they try to associate to the broadcasted ssid there's no problem. All the hidden WLANS are protected with WPA2/AES.
Watching the traps i got some messages that it could help:
DISCONECT_MOBILE_DUE_TO_WLAN_SWITCH: Disconnecting mobile 00:19:5b:7f:60:5c
due to switch of WLANs from 9 to 1

Max EAPOL-key M1 retransmissions exceeded for client 00:19:5b:7f:60:5c.
I believe you can configure up to 16 wlans, but the ap has a maximum of 8. So you can have 8 ssid's on the 802.11b/g radios and 8 ssid's on the 802.11a radio. If you are trying to push out more than 8 ssid's on both, wlan 1-8 will be active and the others will not.
Might be an issues with all the ssid's.... try to remove some and see... what you can do is find that client and see if it is configured right. Maybe its trying to connect to an ssid that puts you over the 8 limit.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
