Integrating OUD and EUS: Preparing Database

After preparing Oracle Unified Directory (OUD), the database itself must be prepared for Enterprise User Security (EUS). Preparing a database involves configuring the database, registering the database, mapping the user(s) or group(s) to a schema.

Preparing the database

Similar to OUD, there is more than one way to achieve this. We will use GUI.

Configuring the Database with OUD info:

Set the required environment variables for database. For example:

export ORACLE_BASE=/opt/app/db/
export ORACLE_SID=dbdev
export ORACLE_HOME=/opt/app/db/11.2.0

Run Net Configuration Assistant (netca) tool to configure OUD for the database.

On database machine, run:

  1. Welcome screen is displayed.
  2. Select Directory Service Usage Configuration and click Next.
  3. Directory Usage Configuration, Directory Type screen is displayed. Select Oracle Internet Directory as the directory type and click Next.
  4. On next screen, Enter the name of the host on which the OUD server is running, its port, SSL port and click Next.
  5. Select the default Oracle Context to use. Select the one that includes your base dn or you will receive TNS error while running dbca.
  6. Click Finish.

NetCA creates an ldap.ora file in the $ORACLE_HOME/network/admin directory which stores the connection information details  about the directory.

Registering the database with the directory service:

The Database Configuration Assistant (DBCA) tool enables  to register the  database with OUD.

To register the database with the directory: Start DBCA using the dbca command.


  1. Welcome screen is displayed.
  2. Select Configure Database options.
  3. Select the database to which EUS will be configured.
  4. Click Next.
  5. Select Yes; register the database. Provide credentials for OUD and a password for wallet.
  6. Select Dedicated server mode and Click Finish.

Once the database is prepared, we need to associate enterprise users to database. Please refer to this post to learn about various user/group mappings available.
