Cisco ASA authenticating to OD through RADIUS

This worked great in 10.5 using the config as already discussed in the thread listed below. In 10.6, this is now no longer an option. http://discussions.apple.com/thread.jspa?messageID=7991110 Can anyone shed light on this subject at all? I have a lot of angry vpn users unable to authenticate. Anyone have any ideas that can be tried?
