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

NAME         top

       pam_timestamp_check - Check to see if the default timestamp is valid

SYNOPSIS         top

       pam_timestamp_check [-k] [-d] [target_user]

DESCRIPTION         top

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

OPTIONS         top

       -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         top

       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         top

       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         top

           auth sufficient pam_timestamp.so verbose
           auth required   pam_unix.so

           session required pam_unix.so
           session optional pam_timestamp.so

FILES         top
