Deploying the IAM Suite and OUD with the Deployment Wizard

Identity & Access Management suite R2 PS2 (11.1.2.2.0) ships with a new deployment tool to automate the installation and configuration of products related to the IAM suite. This tool is named Oracle Identity and Access Management Deployment Wizard.

This tools automates the installation, configuration and integration of WebLogic Server, SOA Suite, Oracle Identity Manager, Oracle Access Management, Oracle Unified Directory, Oracle HTTP Server and Webgates. The tool allows you to select one of three deployment topologies: OIM, OAM or OIM integrated with OAM and OUD.

New Oracle White Paper about Directory Services Integration with Database Enterprise User Security

I’ve written a new Oracle White Paper about Directory Services Integration with
Database Enterprise User Security based on 2 recent posts,https://blogs.oracle.com/sduloutr/entry/oud_eus_take_2_db and https://blogs.oracle.com/sduloutr/entry/oud_eus_take_1_db

OUD&EUS Take 2: DB Accounts Proxy-ed by OUD into existing Directories

By Sylvain Duloutre on Aug 27, 2013

This post is the second 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.

DB Accounts Proxy-ed by OUD into existing Directories

Most enterprises already have existing corporate directories in place, and prefer the EUS implementation. An EUS implementation leverages the existing directory infrastructure and user information base without putting in place synchronization between directories. In this way, OUD acts as a real-time interpreter for Oracle database information requests to user data.

Using OUD enables the database to interact with third-party directories. OUD leverages existing user and group information in the existing third-party directory infrastructure by forwarding LDAP requests and responses back and forth to the third-party directory holding user data. User data, database meta-data such as DB registration information, user/role Mappings, and other EUS specific meta-data are stored locally in OUD, without requiring any schema changes to store EUS configuration in the existing third-party directory.

As of release 11gR2PS1, OUD is certified with EUS to support Active Directory, Oracle Directory Server Enterprise Edition, and Novell eDirectory. Working with these products, OUD eliminates user data duplication and synchronization and consequently lowers total cost of ownership (TCO).

  1. Centralizing Accounts into Microsoft Active Directory

You can integrate Active Directory for password-based authentication or integrate Active Directory with Kerberos authentication.

Active Directory Integration for Password-based authentication

Such a scenario requires deployment of an additional component: the OUD Password Change Notification plug-in (oidpwdcn.dll). Microsoft uses a proprietary implementation to hash passwords in Active Directory that is incompatible with the Oracle DB requirements. The OUD Password Change Notification plug-in isnotified when a password change occurs, and stores hashes in Active Directory. The oidpwdcn dll must be installed on every Active Directory domain controller.

Active Directory Schema extension is required to store the hashed passwords.

The database establishes a connection to OUD. OUD retrieves user data (users and groups) from Active Directory. User passwords are retrieved from the hashed password stored by the OUD Password Change Notification plug-in. EUS metadata are stored and retrieved from OUD.

The database version must be 10.1 or later as earlier versions use a different and incompatible password format.

Active Directory Integration with Kerberos Authentication

In this scenario, Kerberos is used for DB authentication. EUS with DB Kerberos authentication does not require any changes to the database beyond standard EUS configuration. The database establishes a connection to OUD. OUD looks up the requested DB information in Active Directory. All database clients must be Kerberos-enabled to use this option. This capability is only supported with DB version 10.1 or higher.

The database establishes a connection to OUD. OUD retrieves user data (users and groups) from Active Directory. EUS metadata are stored and retrieved from OUD. Access to the hashed user password is not required, so no schema extensions and no Password Change Notification dll have to be deployed on Active Directory.

  1. Centralizing Accounts into ODSEE

The database establishes a connection to OUD. OUD retrieves user data (users and groups) from Oracle Directory Server Enterprise Edition (ODSEE) . EUS metadata are stored and retrieved from OUD.

This integration does not require any changes in the database (beyond what is usually required for EUS, nor for database clients that use username/password authentication.

  1. Centralizing Accounts into Novell eDirectory

The database establishes a connection to OUD. OUD retrieves user data (users and groups) from Novell eDirectory. EUS metadata are retrieved from OUD.

This integration does not require any changes in the database beyond what is usually required for EUS, nor for database clients that use username/password authentication.

Using Novell eDirectory doesn’t require an Oracle password filter. You have to enable Universal Password in eDirectory, and allow the administrator to retrieve the user password. Refer to Novell’s eDirectory documentation on Password Management for more information.

This configuration can only be used with DB versions 10.1 or higher due to incompatible password formats in earlier DB versions.
