PAM_TIMESTAMP(8)            Linux-PAM Manual            PAM_TIMESTAMP(8)

ИМЯ

       pam_timestamp - Authenticate using cached successful
       authentication attempts

СИНТАКСИС

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

ОПИСАНИЕ

       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.

ПАРАМЕТРЫ

       timestampdir=directory
           Specify an alternate directory where pam_timestamp creates
           timestamp files.

       timestamp_timeout=number
           How long should pam_timestamp treat timestamp as valid after
           their last modification date (in seconds). Default is 300
           seconds.

       verbose
           Attempt to inform the user when access is granted.

       debug
           Turns on debugging messages sent to syslog(3).

ТИПЫ МОДУЛЕЙ

       The auth and session module types are provided.

ЗНАЧЕНИЯ, ВОЗВРАЩАЕМЫЕ ФУНКЦИЕЙ

       PAM_AUTH_ERR
           The module was not able to retrieve the user name or no valid
           timestamp file was found.

       PAM_SUCCESS
           Everything was successful.

       PAM_SESSION_ERR
           Timestamp file could not be created or updated.

ПРИМЕЧАНИЯ

       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.

ПРИМЕРЫ

           auth sufficient pam_timestamp.so verbose
           auth required   pam_unix.so

           session required pam_unix.so
           session optional pam_timestamp.so
