PAM_TIMESTAMP_CHECK(8) Linux-PAM Manual PAM_TIMESTAMP_CHECK(8)
pam_timestamp_check - Check to see if the default timestamp is valid
pam_timestamp_check [-k] [-d] [target_user]
With no arguments pam_timestamp_check will check to see if the
default timestamp is valid, or optionally remove it.
-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.
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.
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.
