GnuTLS and FreeRADIUS

Hi everybody, I was searching for some time now and I found a lot of messages from people who wanted to replace the OpenSSL dependencies in FreeRADIUS with GnuTLS. But so far it seems, that nobody really did that, is that right? Or has there been work on that and it failed for some reason? To be honest I have absolutely no idea how complicated that will be but at least I don't expect it to be easy. :) Regards Carolin
