Virtual directories are another solution to provide client applications a single unified view of the user's profile information across multiple systems. Unlike meta-directory services, data is never copied, but served real-time from respective authoritative sources.
There's an increasing trend to drive access control authorization decisions based on information that's reside on other systems like ERP or application specific databases. Policies based on attributes in a user profile can be easily implemented using Virtual Directories. Virtual directory is a cutting-edge technology that eliminates the necessity to copy data between systems and other challenges related to data synchronization.
