Capabilities of Virtual Directories
Virtual directories can have some or all of the following capabilities:
- Aggregate identity data across sources to create a single point of access.
- Create high-availability for authoritative data stores.
- Act as identity firewall by preventing denial-of-service attacks on the primary data stores through an additional virtual layer.
- Support a common searchable namespace for centralized authentication.
- Present a unified virtual view of user information stored across multiple systems.
- Delegate authentication to backend sources through source-specific security means.
- Virtualize data sources to support migration from legacy data stores without modifying the applications that rely on them.
- Enrich identities with attributes pulled from multiple data stores, based on a link between user entries.
Some advanced identity virtualization platforms can also:
- Enable application-specific, customized views of identity data without violating internal or external regulations governing identity data.Reveal contextual relationships between objects through hierarchical directory structures.
- Develop advanced correlation across diverse sources using correlation rules.
- Build a global user identity by correlating unique user accounts across various data stores, and enrich identities with attributes pulled from multiple data stores, based on a link between user entries.
- Enable constant data refresh for real-time updates through a persistent cache.

Famous quotes containing the words capabilities and/or virtual:
“I maintain that I have been a Negro three times—a Negro baby, a Negro girl and a Negro woman. Still, if you have received no clear cut impression of what the Negro in America is like, then you are in the same place with me. There is no The Negro here. Our lives are so diversified, internal attitudes so varied, appearances and capabilities so different, that there is no possible classification so catholic that it will cover us all, except My people! My people!”
—Zora Neale Hurston (1891–1960)
“Neither dead nor alive, the hostage is suspended by an incalculable outcome. It is not his destiny that awaits for him, nor his own death, but anonymous chance, which can only seem to him something absolutely arbitrary.... He is in a state of radical emergency, of virtual extermination.”
—Jean Baudrillard (b. 1929)
