/PWDMINIMUM=value
Specifies the minimum password length in characters. Note that
this value is enforced only by the DCL command SET PASSWORD. It
does not prevent you from entering a password shorter than the
minimum length when you use AUTHORIZE to create or modify an
account. By default, a password must have at least 6 characters.
The value specified by the /PWDMINIMUM qualifier conflicts with
the value used by the /GENERATE_PASSWORD qualifier or the DCL
command SET PASSWORD/GENERATE, the operating system chooses the
lesser value. The maximum value for generated passwords is 10.
