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 users authenticate as themselves. 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.

EXAMPLES

    auth sufficient pam_timestamp.so verbose
    auth required   pam_unix.so

    session optional pam_timestamp.so
