Feature Request - Multiple Password Policies

Please consider supporting more than a single password policy to accommodate different types of FTP accounts.  For example, a very common scenario is to create both user accounts (human interactive logins) and service accounts (for automated jobs). The humans must change their password every 90 days, but the service accounts have a longer expiration period of 180 days (or longer).  In addition, human user passwords are usually 10 characters with complexity, but service accounts (since not usually entered but once) are 30 characters with complexity.   Application of an explicit password policy could be done at the user level or at the group level (e.g. a "Service Account PW Expiry Group" that contains the service accounts).  Multiple policies for different types of users should be a fundamental feature that allows flexibility and more granular password control.
