Virtual Directory Server
Virtualize data between incompatible applications, data stores and directory servers
Virtual Directory Server is a middleware application that abstracts back-end data from client applications, making it possible to modify the presentation of data on the fly. Therefore, you can easily integrate new applications into your existing identity infrastructure without having to alter directory information — your data remains in its original place and format.
The solution has been ported to, and optimized for, all major platforms, allowing it to run in environments where a variety of operating systems are used. It provides a single granular security policy for all back-end repositories and improves overall performance through load balancing and search caching. Quite simply, Virtual Directory Server is the most powerful and flexible software component you can add to improve the operation and administration of your enterprise directory services.
