Hello, I have a debian machine that acts as RADIUS client talking with the Freeradius server. I have configured PAM on the client, so made following changes. 1 - Added radiusd to /etc/pam.d which contains - @include common-auth @include common-account @include common-password @include common-session 2 - Added following line to /etc/pam.d/common_auth auth sufficient pam_radius_auth.so 3 - Added following line to /etc/pam.d/common_account account required pam_radius_auth.so 4- Added following line to /etc/pam.d/common_session session required pam_radius_auth.so 5 - Added server-ip and secret key to /etc/pam_radius_auth.conf Authentication and accounting works fine after I configure the above on the client. As soon as I reboot client, login fails with error - "cannot make/remove an entry for the specified session". Cannot login into the client. Thanks
