Cisco AP1231G as WGB - %DOT11-4-CANT_ASSOC error message

I have a Cisco AP1231G with autonomous IOS running in WorkGroup Bridge (WGB) mode.

However I can't get the device to associate with the root AP; which is a non-Cisco AP, and get the following error message.

%DOT11-4-CANT_ASSOC: Interface Dot11Radio0, cannot associate: WPAIE Invalid unicast suite count: 2

I've scanned Cisco documentation and run searches but I cannot find a doc that explains the cause of this error.

config extract below from Cisco WGB:

Bridging and WGB for the most part is not part of the 802.11 standards. Each vendor may do it a little different. What you probably want to try is to set this AP as a universal WGB. This mode the AP looks more like a client to the AP instead of a WGB.

I can't configure

'station-role workgroup-bridge universal ...'

on the current IOS 12.3(8)JEA so I'll download a later IOS release to see if lets me set that parameter

WGB universal mode does not appear to be supported on Cisco AP1231G even using the latest IOS image 123-8.JEC3 for that model.

Is that the case?

The Configuration Guide for 12.3(8)JEC suggests it is available for the 1200

BUT....previous IOS config guides (12.3(8)JEB) for the 1200 say that universal WGB mode is NOT supported on 1200 universal mode supposed to be supported on the 1231 model or is the latest IOS documentation incorrect?
