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.

MODULE SERVICES PROVIDED

Only the auth service is supported.  

RETURN VALUES

PAM_SUCCESS

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.

PAM_AUTH_ERR

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.

PAM_INCOMPLETE

An application error occurred. pam_securetty was not able to get information it required from the application that called it.

PAM_SERVICE_ERR

An error occurred while the module was determining the user's name or tty, or the module could not open /etc/securetty.

PAM_IGNORE

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.

EXAMPLES

auth  required  pam_securetty.so
auth  required  pam_unix.so
