This illustration shows an overview of Enterprise User Security functionality. It depicts an LDAP-compliant directory where an administrator centrally manages enterprise users and roles. That directory communicates to Oracle9i databases to which clients connect using Net Manager/SSL. Each of the components (clients, servers, directory) has a wallet (required for SSL communications) which stores their credentials. Administrators and/or users utilize Oracle wallet manager to request and manage certificates from a non-Oracle certificate authority.
