- pam_securetty.so [debug]
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.
- Print debug information.
- 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 /etc/securetty file.
MODULE TYPES PROVIDED
Only the auth module type is provided.
- The user is allowed to continue authentication. Either the user is not root, or the root user is trying to log in on an acceptable device.
- Authentication is rejected. Either root is attempting to log in via an unacceptable device, or the /etc/securetty file is world writable or not a normal file.
- An application error occurred. pam_securetty was not able to get information it required from the application that called it.
- An error occurred while the module was determining the user's name or tty, or the module could not open /etc/securetty.
- The module could not find the user name in the /etc/passwd file to verify whether the user had a UID of 0. Therefore, the results of running this module are ignored.
