DirectPlay provides user and message authentication (digital signing) support through the Windows® Security Support Provider Interface (SSPI). The default security package that DirectPlay uses is called NTLM Security Support Provider.
A DirectPlay application can choose to use a different SSPI security package when it creates a session by using DirectPlay4.SecureOpen. For example, DPA (Distributed Password Authentication) Security Support Provider is another security package that organizations can use to provide membership services to a large customer base (hundreds of thousands). This security package is available through the Microsoft Commercial Internet Services (MCIS) Membership Server.
