need info about radius+SSH

Hello all I have freeradius installed on solaris 10. I want to do the configuration in such a way that, when a user connects to this machine using ssh, the user authentication is done using the RADIUS server. I have added the following line to /etc/pam.conf on solaris machine. ssh auth sufficient pam_radius_auth.so.1 But I do not see any request sent to radius server when a user connects to the machine using ssh. However I have tried similar configuration for telnet by adding following line to /etc/pam.conf telnet auth sufficient pam_radius_auth.so.1 And this configuration works fine. Can some one please tell me what am I missing?? Thanks and regards. -Vishwa
