ViewDS Directory Server. Not just another LDAP directory.
ViewDS Directory Server is an identity and access management platform offering a fast, scalable and flexible identity management infrastructure optimized to support high-speed searches on hierarchically structured data as well as providing attribute-based access control, role-based access control, and fine-grained authorization services.
Unlike ordinary, application-specific registry and discovery services, ViewDS Directory Server provides a comprehensive yet flexible discovery server with no built-in preconceptions about the real-world objects and the properties that must be registered and subsequently discovered. The result is a single service that satisfies the registration and discovery requirements of a range of applications and purposes across a variety of industries.
Optimized for fast searches of large, complex, hierarchically-structured data sets, yet lightweight, efficient, highly scalable, and secure, Directory Server is used extensively by enterprise, government, military, aviation and health organizations throughout the world.
