Unfortunately it seems that we don't have any choice. We need TLS 1.2 which seems not to be supported in OpenSSL. So, we will start with modifying the EAP-TLS module in order to use GnuTLS. I know it is a terrible solution to have both TLS libraries in FreeRADIUS, but at the moment, we don't have the resources to try to migrate FreeRADIUS completely. I hope that we won't see side effects when migrating one module - we'll see... Is there already any known problem with that approach?

@Jouni: I will start grepping through wpa_supplicant and hope that I can reuse as much code as possible.
