NAME

     pam_securetty -- SecureTTY PAM module


SYNOPSIS

     [service-name] module-type control-flag pam_securetty [options]


DESCRIPTION

     The SecureTTY service module for PAM provides functionality for only one
     PAM category: account management.  In terms of the module-type parameter,
     this is the ``account'' feature.  It also provides null functions for
     authentication and session management.

   SecureTTY Account Management Module
     The SecureTTY account management component (pam_sm_acct_mgmt()), returns
     failure if the user is attempting to authenticate as superuser, and the
     process is attached to an insecure TTY.  In all other cases, the module
     returns success.

     A TTY is considered secure if it is listed in /etc/ttys and has the
     TTY_SECURE flag set.

     The following options may be passed to the authentication module:

     debug    syslog(3) debugging information at LOG_DEBUG level.

     no_warn  suppress warning messages to the user.  These messages include
              reasons why the user's authentication attempt was declined.
