Hi, I configured Freeradius to use PAP method with users file. The password is stored in clear text is stored in clear text in the user file and it works well. Now I want to use other mode of user storing with PAP method. (exemple MD5 with the user file locatedt in /freeradius-1.1.6/src/tests/digest-auth-MD5) 1- How to tell frreeradius that the user password is stored in clear text, or digest, or MD5 hashed, etc ?? I tried to copy the content of "digest-auth-MD5" in the "users" file and I got this errror : Errors reading /opt/freeradius/etc/raddb/users radiusd.conf[1067]: files: Module instantiation failed. radiusd.conf[1852] Unknown module "files". radiusd.conf[1788] Failed to parse authorize section. I want to test also CHAP method, how to tell radius to use this method in stead of PAP? thanks
