PAM_TIMESTAMP_CHECK(8)						 Linux-PAM Manual					    PAM_TIMESTAMP_CHECK(8)

NAME
pam_timestamp_check - Check to see if the default timestamp is valid SYNOPSIS
pam_timestamp_check [-k] [-d] [target_user] DESCRIPTION
With no arguments pam_timestamp_check will check to see if the default timestamp is valid, or optionally remove it. OPTIONS
-k Instead of checking the validity of a timestamp, remove it. This is analogous to sudo's -k option. -d Instead of returning validity using an exit status, loop indefinitely, polling regularly and printing the status on standard output. target_user By default pam_timestamp_check checks or removes timestamps generated by pam_timestamp when the user authenticates as herself. When the user authenticates as a different user, the name of the timestamp file changes to accommodate this. target_user allows to specify this user name. RETURN VALUES
0 The timestamp is valid. 2 The binary is not setuid root. 3 Invalid invocation. 4 User is unknown. 5 Permissions error. 6 Invalid controlling tty. 7 Timestamp is not valid. 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 FILES

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. SEE ALSO
