/PWDEXPIRED (default)
/NOPWDEXPIRED
Specifies the password is valid for only one login. A user must
change a password immediately after login or be locked out of the
system. The system warns users of password expiration. A user can
either specify a new password, with the DCL command SET PASSWORD,
or wait until expiration and be forced to change. By default, a
user must change a password when first logging in to an account.
The default is applied to the account only when the password is
being modified.
