"files" is running after "eap" here, so when you set:
DEFAULT EAP-TLS-Require-Client-Cert = yes
...it's after the EAP module has already run, so is little use.
Either move the "files" module before "eap", or use unlang to set it:
authorize {
...
update control {
EAP-TLS-Require-Client-Cert = yes
}
eap
...
}
