For Cisco router login /enable authentication I want to use active directory authentication. I have installed Red Hat Linux 4 (2.6.9-5.EL #1) with Samba. I have also installed OpenSSL 0.9.8e 23 Feb 2007 and FreeRadius 1.1.7. I see RHL OS installation also put openssl (some old version of 2003) in /usr/bin directory. After following FreeRADIUS Tutorial for AD integration I am not able to start radius daemon as it complains - radiusd.conf[10]: eap: Module instantiation failed. radiusd.conf[1962] Unknown module "eap". radiusd.conf[1909] Failed to parse authenticate section. Please advise what am I missing? While compiling openssl and freeradius I am using default option. Somewhere I read - "you want to use TLS or TTLS or PEAP, but have compiled the server without TLS support. Install openssl and the corresponding development libraries (often called openssl-devel) and recompile the server." Also one link advises to configure freeradius as following - ./configure --with-rlm-eap-tls-include-dir=/usr/kerberos/include/ Here problem is that I donot see /usr/kerberos/include path. Please suggest the right option for compiling openssl, freeradius and advisory.
