Error with EAP-PEAP

[Vincenzo Agosti <vagosti@unisa.it>]

Hi,
i would to configure my server radius for 802.1x authentication.
But when i modify my eap.conf file and then start radius i have this  
error message:

rlm_eap: Failed to link EAP-Type/tls: rlm_eap_tls.so: cannot open  
shared object file: No such file or directory

What's happen? How can i remove these error?
This is my eap.conf file...

        eap {
                default_eap_type = peap
                timer_expire     = 60
                ignore_unknown_eap_types = no
                cisco_accounting_username_bug = no

                md5 {
                }
                leap {
                }
                gtc {
                        auth_type = PAP
                }
                tls {
                        private_key_password = whatever
                        private_key_file = ${raddbdir}/certs/cert-srv.pem
                        #certificate_file = ${raddbdir}/certs/cert-srv.pem
                        CA_file = ${raddbdir}/certs/demoCA/cacert.pem
                        dh_file = ${raddbdir}/certs/dh
                        random_file = ${raddbdir}/certs/random
                        fragment_size = 1024
                        include_length = yes
                }

                #ttls {
                #       default_eap_type = md5
                #       copy_request_to_tunnel = no

                #       use_tunneled_reply = no
                #}

                peap {
                        default_eap_type = mschapv2
                #       copy_request_to_tunnel = no
                #       use_tunneled_reply = no
                #       proxy_tunneled_request_as_eap = yes
                }
                mschapv2 {
                }
        }

Thanks
