Today's economic environment requires organizations to maximize their investment in technology.  Since databases are critical components of enterprise IT infrastructure that house sensitive corporate data, database user accounts and privileges should be centralized and integrated into enterprise identity management framework. Enterprise User Security (EUS), an Oracle Database Enterprise Edition feature, leverages the Oracle Directory Services and gives you the ability to centrally manage database users and role memberships in an LDAP directory. Enterprise User Security reduces administration cost, increases security, and improves compliance through centralized database user account management, centralized provisioning and de-provisioning of database users, centralized password management and self-service password reset, and centralized management of authorizations using global database roles.
