Hello,Alan. Thank you for you response. Alan wrote:
This is an issue with PAM on the client machine. Some other module is doing password checking. When the password check fails, it re-sets the password to "INCORRECT". That password is then sent to the pam_radius module. Go fix the client so that the PAM modules don't change the password.
My /etc/pam.d/sshd file contains the following settings: -bash-3.2# cat sshd #%PAM-1.0 auth sufficient pam_radius_auth.so debug auth include system-auth account sufficient pam_radius_auth.so account required pam_nologin.so account include system-auth password sufficient pam_radius_auth.so password include system-auth session sufficient pam_radius_auth.so session optional pam_keyinit.so force revoke session include system-auth session required pam_loginuid.so
