(RADIATOR) decrypt problems

[Miro Majcen]

hello, 

i have been trying to get my cisco 3640 to authenticate via radiator. While the exact config works on 26xx , it doesn't work with 3600 Software (C3640-I-M), Version 12.2(5), RELEASE SOFTWARE (fc1)

here is the debug log, any idea what could be causing this ?
