I think you talk about the protocol. I talk about cipher suites. 
FreeRADIUS disables SSLv2 and SSLv3 *protocols* using SSL_OP_NO_SSLv2 
and SSL_OP_NO_SSLv3 OpenSSL context options. But it does not disable 
SSLv2 and SSLv3 cipher suites. cipher suites are set in eap module 
configuration as cipher_list = "DEFAULT". This will result in all cipher 
suites, SSLv2, SSLv3, TLSv1, TLSv1.2, etc. I think Clement can try to 
set it to cipher_list = "DEFAULT:!SSLv2:!SSLv3". Maybe that helps him, I 
don't know.
