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