If DevicePasswordHistory is not included in a response, then a client SHOULD treat this value as 0.

If the value of the DevicePasswordHistory element is greater than 0, and the value of the DevicePasswordEnabled element (section 2.2.2.25) is set to TRUE (1), the client disallows the user from using a stored prior password after a password expires.
