Definition - What does Metadirectory mean?
A metadirectory resource is a centrally managed data integration service. It may manage data transactions between multiple directories, or between directories and databases, and these types of services include various features to filter data or otherwise evaluate or monitor data in transit.
Techopedia explains Metadirectory
In enterprise technology, the metadirectory has been tied to a discipline called identity management, where businesses comprise data sets on each individual employee or user. Identity management is done partly for security reasons, and partly to help identify people as parts of business processes. A metadirectory can be useful in routing all of this data around the network. However, some technology professionals are now questioning whether the metadirectory has outlasted its usefulness, and whether companies are moving away from this format in terms of identity management and access services.
