[Freeradius][EAP] Проблемы с использованием EAP-GTC для внутренней аутентификации фазы 2.

Я пытаюсь настроить аутентификацию EAP-TTLS/GTC. На этапе 1 сервер предлагает EAP-TTLS, и клиент принимает его. Клиент настроен на автоматический для фазы 2, и я ожидаю, что сервер предложит GTC для аутентификации фазы 2, чего не происходит. Может кто-нибудь помочь мне понять, чего не хватает в файле conf.

eap {
            default_eap_type = ttls
            timer_expire     = 60
            ignore_unknown_eap_types = no
            cisco_accounting_username_bug = no
            max_sessions = 4096
            md5 {
            }
            leap {
            }
            gtc {
                    auth_type = Local
            }
            tls {
                    certdir = ${confdir}/certs_freeradius2
                    cadir = ${confdir}/certs_freeradius2
                    private_key_password = radius
                    private_key_file = /etc/freeradius/certs/server.key
                    certificate_file = /etc/freeradius/certs/server.pem
                    CA_file = /etc/freeradius/certs/ca.pem
                    dh_file = ${certdir}/dh
                    random_file = ${certdir}/random
                    fragment_size = 1024
                    include_length = yes
                    cipher_list = "DEFAULT"
                    make_cert_command = "${certdir}/bootstrap"
                    cache {
                    }
            }
            ttls {
                    default_eap_type = gtc
                    copy_request_to_tunnel = yes
                    use_tunneled_reply = yes
                    virtual_server = "inner-tunnel"
            }
            peap {
                    default_eap_type = mschapv2
                    copy_request_to_tunnel = yes
                    use_tunneled_reply = yes
                    proxy_tunneled_request_as_eap = yes
                    virtual_server = "inner-tunnel"
            }
            mschapv2 {
            }
    }

Другая вещь, которую я хотел бы отметить, это то, что я вижу инициацию и обработку gtc в radius.log, но я не думаю, что фаза 2 была успешной.
