I have been bitten by differences in PAM implementation and documention, spesifically with RedHats /bin/login from util-linux-2.10f and pam_console. In the pam documentation it is said: <CLIP> PAM_TTY The terminal name: prefixed by /dev/ if it is a device file; for graphical, X-based, applications the value for this item should be the $DISPLAY variable. </CLIP> However, RedHats /bin/login and pam_console hack _remove_ the /dev/ from tty device file names. My own application which followed the documentation did not work with pam_console. Which one is correct, RedHat implementation or pam documentation? And if RH is in error, will it ever be fixed? - Jani
