No client cert request when configured EAP-TLS-Require-Client-Cert

Hi, I have strange behavior on my freeradius. I try to make it ask for client certificate as part of EAP-TTLS authentication. I added the configuration EAP-TLS-Require-Client-Cert = Yes to users configuration file as control for my username. And got the following LOG TLS_accept: SSLv3 write server done A [ttls] TLS_accept: SSLv3 flush data [ttls] TLS_accept: Need to read more data: SSLv3 read client certificate However, the sniffing shows no client certificate sending and there is no cert request sent by the server You can see it below Thanks for your help.
