NAME
pam_timestamp - Authenticate using cached successful authentication attempts

SYNOPSIS

pam_timestamp.so [timestamp_timeout=number] [verbose] [debug]

DESCRIPTION

In a nutshell, pam_timestamp caches successful authentication attempts, and allows you to use a recent successful attempt as the basis for authentication. This is similar mechanism which is used in sudo.

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.

OPTIONS

timestamp_timeout=number

verbose

debug

MODULE TYPES PROVIDED

The auth and session module types are provided.

RETURN VALUES

PAM_AUTH_ERR

PAM_SUCCESS

PAM_SESSION_ERR

NOTES

Users can get confused when they are not always asked for passwords when running a given program. Some users reflexively begin typing information before noticing that it is not being asked for.

EXAMPLES

auth sufficient pam_timestamp.so verbose
auth required   pam_unix.so
session required pam_unix.so
session optional pam_timestamp.so
