The guide does not say anything about copying any file to the client. So i assumed that it is not need it, but still after configuring the supplicant as the tutorial explains(for permitting the use of an unknown certificate) i always get "certificate not found" and no request reached the freeradius server from the supplicant.

Just to clarify, my freeradius server is working well with everything else(freeradius+mysql+PAP+EAP and windows supplicant can connect too), just having troubles with certificates part.
