PAM_TIMESTAMP_CHECK

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 one 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.
