Explanation:
A meta-directory gathers the necessary information from multiple sources and storesthem in one central directory. This provides a unified view of all users’ digitalidentity information throughout the enterprise. The meta-directory synchronizesitself with all of the identity stores periodically to ensure the most up-to-dateinformation is being used by all applications and IDM components within theenterprise. A virtual directory plays the same role and can be used instead of ameta-directory. The difference between the two is that the meta-directory physicallyhas the identity data in its directory, whereas a virtual directory does not andpoints to where the actual data resides. When an IDM component makes a call to avirtual directory to gather identity information on a user, the virtual directorywill point to where the information actually lives.
