"""A demo of using win32net.NetValidatePasswordPolicy.
Example usage:
% NetValidatePasswordPolicy.py --password=foo change
which might return:
> Result of 'change' validation is 0: The operation completed successfully.
or depending on the policy:
> Result of 'change' validation is 2245: The password does not meet the
> password policy requirements. Check the minimum password length,
> password complexity and password history requirements.
Adding --user doesn't seem to change the output (even the PasswordLastSet seen
when '-f' is used doesn't depend on the username), but theoretically it will
also check the password history for the specified user.
% NetValidatePasswordPolicy.py auth
which always (with and without '-m') seems to return:
> Result of 'auth' validation is 2701: Password must change at next logon
