The radius log keep saying that

Auth: Login incorrect (rlm_chap: Clear text password not available

I already tried different password attribute

eg: CHAP-Password, Cleartext-Password and User-Password

All won't work

I am also seaching the google and FAQ too

The FAQ has *clear* documentation on how to configure the server with a "known good" password.

Could you help what I am doing wrong?
