OUD&EUS Take 1: DB Accounts Stored in OUD

This post is the first one of a serie focusing on Enterprise User Security (EUS) and Oracle Unified DIrectory (OUD).

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. EUS reduces administration costs and increases security

Storing DB Accounts in OUD

OUD is specifically tailored to work seamlessly with EUS. Database user information, passwords and privileges information for a database or for a database domain can be stored in OUD.

EUS can leverage existing user and group information stored in OUD to provide single password authentication and consistent password policy across enterprise applications. User data, database meta-data, such as DB registration information, user/role Mappings, and other EUS specific meta-data are stored in OUD using a specific, supported, read-to-use LDAP schema. These meta-data are stored in a separate OUD suffix, called Oracle Context, making a clean logical separation between EUS data and user information that can be shared across applications.

In addition to providing centralized database user management, Enterprise EUS provides three different methods of user authentication: X.509 certificate authentication (introduced in DB 8i); Password-based authentication (since DB 9i); and authentication via Kerberos (since DB 10g). OUD support for Password-based authentication for EUS was introduced in OUD 11gR2. The other authentication methods were introduced in OUD 11gR2PS1.

In the password authentication scenario, the database does not perform user authentication via LDAP bind to OUD. Instead the database collects user credentials, hashes the password, and compares the password hash value retrieved from OUD. More detailed information about EUS can be found in the Enterprise User Administrator's Guide in the Database documentation section on OTN.


Comments:

How many MB of schema mods do you need to load before you can make use of EUS? Is it still anything that Oracle ever developed or is it cut down to just EUS requirements?

OUD comes with the EUS schema installed OOTB, so you don't have to deal about schema. Just make sure to enable EUS support when you configure OUD instances.

Is OUD free for EUS? or any license cost involved?

OUD requires the ODS+ licence as decribed at http://www.oracle.com/us/products/middleware/identity-management/oracle-directory-services/directoryservicesplus-ds-404374.pdf
It gives you the rights to use all Oracle Directory products.
