I followed documentation from http://www.freeradius.org/pam_radius_auth and have configured pam for RADIUS. I added the pam_radius_auth.so into /etc/pam.d/login . I also copied the conf file to /etc/raddb/server and gave it an server IP address. In the log file i keep getting the errror "No server found in the configuration file" and i see that radius does not get invoked. Any thoughts/ideas on this error is greatly appreciated Thanks Sangeetha Ganesh
