Active Directory Interoperability Program

Provides the Kerberos PAC authentication and key distribution protocol used to authenticate two principals to each other, and establish a cryptographic key that the two can use to secure any messages

The license may be used in client-side and server-side implementations

Scenarios include communicating for Windows 2000-specific group membership authorization data carried in the field of a Kerberos ticket for use by servers in performing access control

Provides authentication and authorization service protocols used between Windows clients and Windows domain controllers

The license is for use in server-side implementations (e.g., application and Web servers)

Scenarios include communicating with Windows client logon and security subsystems for authentication, authorization and access control, policy enforcement, or usage accounting and audit information data packets

Provides authentication and authorization service protocols used between Windows clients and Windows domain controllers.

The license is for use in client-side implementations (on desktops, workstations or other devices, including, e.g., servers acting as clients)

Scenarios include communicating with Windows domain controllers for local logon and communicating with other Windows servers for network access using Windows domain user credentials

Provides group policy service protocols used between Windows clients and Windows servers.

The license is for use in client-side implementations (on desktops, workstations or other devices, including, e.g., servers acting as clients)

Scenarios include communicating with Windows domain controllers for application of group policy for , enabling the management of configuration and other policies for all machines and users in a domain

Provides authentication and authorization service protocols used between Windows member servers and Windows clients, and between Windows member servers and Windows domain controllers

The license is for use in server-side implementations (e.g., application and Web servers)

Scenarios include communicating with Windows clients and servers and with Windows domain controllers for pass-through authentication of remote requests from Windows clients and servers to Windows domain controllers
