Hey there, I have a home server which only supports pap. FreeRADIUS were configured to establish eap-ttls-pap and then proxy the inner request to my home server. Although It configured to use pap but it doesn’t send user clear-text-password to my home server. Here is the output of freeradius -X: oot@eduroam:/etc/freeradius# freeradius -X Server was built with: accounting : yes authentication : yes ascend-binary-attributes : yes coa : yes control-socket :
