pam_timestamp(8)         System Administrator's Manual        pam_timestamp(8)



NAME
       pam_timestamp  -  authenticate  using  cached successful authentication
       attempts

SYNOPSIS
       auth sufficient /lib/security/pam_timestamp.so
       session optional /lib/security/pam_timestamp.so


DESCRIPTION
       In a nutshell, pam_timestamp caches successful authentication attempts,
       and  allows  you  to  use  a recent successful attempt as the basis for
       authentication.

       When an application opens a session using  pam_timestamp,  a  timestamp
       file  is  created  in the timestampdir directory for the user.  When an
       application attempts to authenticate the  user,  a  pam_timestamp  will
       treat  a sufficiently- recent timestamp file as grounds for succeeding.


ARGUMENTS
       debug  turns on debugging via syslog(3).

       timestampdir=name
              tells pam_timestamp.so where to place and search  for  timestamp
              files.   This  should match the directory configured for sudo(1)
              in the sudoers(5) file.

       timestamp_timeout=number
              tells pam_timestamp.so how long it should treat timestamp  files
              as  valid after their last modification date.  This should match
              the value configured for sudo(1) in the sudoers(5) file.

       verbose
              attempt to inform the user when access is granted.


EXAMPLE
       /etc/pam.d/some-config-tool:
       auth sufficient /lib/security/pam_timestamp.so  verbose  auth  required
       /lib/security/pam_unix.so
       session    required    /lib/security/pam_permit.so   session   optional
       /lib/security/pam_timestamp.so


CAVEATS
       Users can get confused when they aren't always asked for passwords when
       running  a given program.  Some users reflexively begin typing informa-
       tion before noticing that it's not being asked for.
