pam_timestamp
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
information before noticing that it's not being asked for.
