A default Enterprise User Security deployment requires Oracle Internet Directory (OID), a scalable, secure and standards-based directory, while Oracle Virtual Directory (OVD) enables enterprises to implement EUS leveraging their existing directory infrastructure e.g. Active Directory or SunOne Directory so as to lower total cost of ownership (TCO).

This paper presents the EUS deployment options available using OID and OVD, and the use cases will help determine when one is more appropriate than the other based on customer environment.
