Abstract
A domain controller (DC) side plugin supports one time passwords natively in Kerberos, Part of the key material is static and the other part is dynamic, thereby leveraging properties unique to each to securely support one time passwords in an operating system. The user is permitted to type in the one time passcode into a logon user interface. Rather than calling the SAM APIs to get the static passwords, vendors may register callbacks on the DC to plugin their algorithm. These callback functions will return the dynamically calculated passcodes for the user at a specific point in time. This passcode will then be treated as a normal password by the DC.
