   7 SYNOPSIS
   8      pam_timestamp.so.1 [debug] [timeout=min]
   9 
  10 DESCRIPTION
  11      The pam_timestamp module caches successful tty-based authentication
  12      attempts by creating user's directories and per tty timestamp files in
  13      the common timestamp directory /var/run/tty_timestamps.  Next
  14      authentication, if the timestamp file exist and not expired, the user
  15      will not be asked for a password, otherwise timestamp file will be
  16      deleted and user will be prompted to enter a password.
  17 
  18      The PAM items PAM_USER, PAM_AUSER and PAM_TTY are used by this module.
  19      pam_timestamp is normally configured as sufficient and must be used in
  20      conjunction with the modules that support the UNIX authentication, which
  21      are pam_authtok_get(5), pam_unix_cred(5) and pam_unix_auth(5).  Proper
  22      authentication operation requires pam_unix_cred(5) be stacked above
  23      pam_timestamp.
  24 
  25 OPTIONS
  26      debug   Provides syslog(3) debugging information at the LOG_AUTH |
  27              LOG_DEBUG level.
  28 
  29      timeout
  30              Specifies the period (in minutes) for which the timestamp file is
  31              valid.  The default value is 5 minutes.

  33 FILES

  37 EXIT STATUS
  38      PAM_SUCCESS
  39              Timestamp file is not expired.
  40 
  41      PAM_IGNORE
  42              The pam_timestamp module was not able to retrieve required
  43              credentials or timestamp file is expired or corrupt.
