The password lifetime for the account elapsed. The password for the
account did not change before the password lifetime was over.
To re-enable the account, you can either assign a new password
as described in
``Setting or changing a user password''
or unlock the account as described above
(in which case the user is
forced to set the password at login time). Advise users
to change their passwords before the lifetime expires.
A number of unsuccessful tries were made on the account, exceeding the
threshold number you set for locking it. These tries may not have
all been made on the same terminal. Before re-enabling the account, it is a
good idea to determine the cause for the lockout.
It may be that the user is a poor typist or that
or another person is trying to lock the account and knows
this is a way to do it, or that a real attempt to penetrate the
account is being made. You may want to adjust the
threshold upward or downward, depending on the nature
of the system users, the value of the data, and the
accessibility of the system to outsiders.
