Apple clients suddenly can't authenticate to EAP-MSCHAPV2

[Casartello, Thomas]

Having a bizarre problem that started due to someone in my department deleting the samba computer account for my freeradius machine. I recreated it and for a time everything went back to normal, but later that afternoon all of my apple clients can simply not connect to our 802.1x enabled wireless network. We are using Cisco wireless controllers. Radiusd -X doesn't seem to be giving me enough debug output. Is there any suggestion as to drill down further to see what is going on here. I am having no issues with my Windows 7 clients and Windows mobile devices. Simply not getting enough information. Everything has been working fine for months and I don't understand why all of the sudden this is going on and why its only affecting Apple IOS devices and iMacs so far. Here's an example output.  This simply loops over and over again:
