Run ADSIedit

adsiedit.msc

Connect to the naming context

Expand <Domain> --> System --> Password Settings Container
Right-click & create Object


Enter Attribute Values:

CN StaffPasswords ()
msDS-PasswordSettingsPrecedence 10
msDS-PasswordReversibleEncryptionEnabled False
msDS-PasswordHistoryLength 25
