If not and it was +built with vendordir support, it will use <vendordir>/securetty. pam_securetty +also checks that the securetty files are plain files and not world writable. It +will also allow root logins on the tty specified with console= switch on the +kernel command line and on ttys from the /sys/class/tty/console/active. + +This module has no effect on non-root users and requires that the application +fills in the PAM_TTY item correctly. + +For canonical usage, should be listed as a required authentication method +before any sufficient authentication methods. + +OPTIONS + +debug + + Print debug information. + +noconsole + + Do not automatically allow root logins on the kernel console device, as + specified on the kernel command line or by the sys file, if it is not also + specified in the securetty file. + +EXAMPLES + +auth required pam_securetty.so +auth required pam_unix.so + + +AUTHOR + +pam_securetty was written by Elliot Lee <sopwith@cuc.edu>. + |
