name : PAM-configuration.txt PAM configuration is very distribution specific. This is reason why upstream util-linux package does not install any PAM config files. Expected PAM config files: login(1): /etc/pam.d/remote - for -h command line option /etc/pam.d/login - regular login su(1): /etc/pam.d/su-l - for --login command line option /etc/pam.d/su - regular su runuser(1): /etc/pam.d/runuser-l - for --login command line option /etc/pam.d/runuser - regular su Note that runuser requires only "session" setting (and for example "auth sufficient pam_rootok.so" dummy line). chfn(1): /etc/pam.d/chfn chsh(1): /etc/pam.d/chsh
