NIS vs. LDAP Integration:
The NIS integration might be a better choice if you already deployed NIS in your environment, and all you want is to migrate the NIS server to use Windows 2000 so that you can have a central server for both UNIX and Windows 2000 user accounts. However, this integration limits the server and client communication to what NIS can provide.
LDAP directory technology has been widely accepted by the industry. It provides distributed, scalable and flexible services for an enterprise environment. It also avoids the dependency on UNIX connectivity products from Microsoft. If your goal is to adopt the new technique and take advantage of current functionality as well as future enhancements, the LDAP integration would be a better choice.
