NAME <\/a> <\/h2>\n

pam_timestamp \u2212 Authenticate using cached successful authentication attempts<\/p>\n

SYNOPSIS <\/a> <\/h2>\n\n\n
<\/td>\n\n

pam_timestamp.so<\/b> [timestampdir=directory<\/i>] [timestamp_timeout=number<\/i>] [verbose] [debug]<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

DESCRIPTION <\/a> <\/h2>\n

In a nutshell, pam_timestamp<\/i> 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<\/b>.<\/p>\n

When an application opens a session using pam_timestamp<\/i>, a timestamp file is created in the timestampdir<\/i> directory for the user. When an application attempts to authenticate the user, a pam_timestamp<\/i> will treat a sufficiently recent timestamp file as grounds for succeeding.<\/p>\n

OPTIONS <\/a> <\/h2>\n

timestampdir=<\/b>directory<\/i><\/p>\n

Specify an alternate directory where pam_timestamp<\/i> creates timestamp files.<\/p>\n

timestamp_timeout=<\/b>number<\/i><\/p>\n

How long should pam_timestamp<\/i> treat timestamp as valid after their last modification date (in seconds). Default is 300 seconds.<\/p>\n

verbose<\/b><\/p>\n

Attempt to inform the user when access is granted.<\/p>\n

debug<\/b><\/p>\n

Turns on debugging messages sent to syslog<\/b>(3).<\/p>\n

MODULE TYPES PROVIDED <\/a> <\/h2>\n

The auth<\/b> and session<\/b> module types are provided.<\/p>\n

RETURN VALUES <\/a> <\/h2>\n

PAM_AUTH_ERR<\/p>\n

The module was not able to retrieve the user name or no valid timestamp file was found.<\/p>\n

PAM_SUCCESS<\/p>\n

Everything was successful.<\/p>\n

PAM_SESSION_ERR<\/p>\n

Timestamp file could not be created or updated.<\/p>\n

NOTES <\/a> <\/h2>\n

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.<\/p>\n

EXAMPLES <\/a> <\/h2>\n

auth sufficient pam_timestamp.so verbose
auth required pam_unix.so<\/p>\n

session required pam_unix.so
session optional pam_timestamp.so<\/p>\n
