我正在尝试设置 EAP-TTLS/GTC 身份验证。在第一阶段，服务器提供 EAP-TTLS 并且客户端接受它。客户端在第 2 阶段设置为自动，我希望服务器为第 2 阶段身份验证提供 GTC，但没有发生。有人可以帮我弄清楚conf文件中缺少什么。
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 {
}
}
我想指出的另一件事是，我确实在 radius.log 中看到了 gtc 启动和处理，但我认为第 2 阶段并不成功。
