Hello, I'm using the freeradius 2.10 server that comes with Ubuntu 11.10. I'm unable to set it up so as to authenticate incoming requests from the Unix username/passwords stored in /etc/{passwd, shadow}. Here is a description of my setup. I've setup wifi security on my wireless router to WPA-Enterprise and entered the IP address of the radius server in the router to that of a Linux machine running freeradius. Here's a description of all the changes I made to /etc/freeradius directory to even reach the point to make it partially work: 1) chown -R freerad /etc/freeradius The above is needed as Ubuntu seems to install every file there as root and thus the freeradius server which runs as user freerad isn't able to read the configuration files. 2) Modified /etc/freeradius/clients.conf to accept requests from my router's IP address. Also added the shared key testing123 there - which is the same that was put in the router while configuring it with a radius server. 3) Changed the 'group =' setting inside /etc/freeradius/radiusd.conf to make it 'shadow' to enable it to lookup /etc/shadow. 4) Uncommmented the keyword 'unix' in both /etc/freeradius/sites-enabled/{inner-tunnel,default} 5) Modified /etc/default/freeradius to pass option '-X' to the freeradius server. I've tried using both Windows 7 as well as an iPad as a client to connect using wifi. Each time, the freeradius server running on my Linux box denies the requests. I should mention that a 'radtest' succeeds - so I'm entering the username/passwd correctly. I'm attaching the output of the freeradius server when iPad is used. In a separate email I'll also attach the output from Windows 7 (to avoid going over the 100KB message limit in this email). Any help is appreciated. - Mohit
