NAME

6       pam_timestamp_check - Check to see if the default timestamp is valid
7

SYNOPSIS

9       pam_timestamp_check [-k] [-d] [target_user]
10

DESCRIPTION

12       With no arguments pam_timestamp_check will check to see if the default
13       timestamp is valid, or optionally remove it.
14

OPTIONS

16       -k
17           Instead of checking the validity of a timestamp, remove it. This is
18           analogous to sudo's -k option.
19
20       -d
21           Instead of returning validity using an exit status, loop
22           indefinitely, polling regularly and printing the status on standard
23           output.
24
25       target_user
26           By default pam_timestamp_check checks or removes timestamps
27           generated by pam_timestamp when the user authenticates as herself.
28           When the user authenticates as a different user, the name of the
29           timestamp file changes to accommodate this.  target_user allows one
30           to specify this user name.
31

NOTES

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