Note that "minlen" is not just a number of characters in the password. It is a computed value and includes
the number of characters in the password, as well as complexity factors from the password itself. For
example, if and how many capitals, numbers, or special characters it has. In addition to the number of
characters in the new password, credit (of +1 in length) is given for each different kind of character (other,
upper, lower, and digit). The default for this parameter is 9.
