### NAME

pam_lastlog - login accounting PAM module

### SYNOPSIS

[service-name] module-type control-flag ```pam_lastlog` [options]

### DESCRIPTION

The login accounting service module for PAM provides functionality for only one PAM category: session management. In terms of the module-type parameter, this is the `````session`'' feature.

#### Login Accounting Session Management Module

The login accounting session management component provides functions to initiate (pam_sm_open_session(``)) and terminate (pam_sm_close_session(``)) sessions. The pam_sm_open_session(``) function records the session in the utmp(5), utmpx(5), wtmp(5), wtmpx(5), lastlog(5), and lastlogx(5) databases. The pam_sm_close_session(``) function does nothing.

The following options may be passed to the authentication module:

debug
  syslog(3) debugging information at ```LOG_DEBUG` level.

no_nested
  Don't update records or print messages if the user is ``nested'', i.e. logged in on the same tty on top of another user.

no_warn
  suppress warning messages to the user.

no_fail
  Ignore I/O failures.
