Oracle Net Configuration Assistant is a wizard-based tool with a graphical user interface. Its primary uses are to configure basic Oracle Net network components, such as listener names and protocol addresses, and to configure your Oracle home for directory server usage. The latter use is what makes this tool important for configuring Enterprise User Security.
If you use Domain Name System (DNS) discovery (automatic domain name lookup) to locate Oracle Internet Directory on your network, then this assistant is not necessary. Note that using DNS discovery is the recommended configuration. See Oracle Fusion Middleware Administrator's Guide for Oracle Internet Directory for information about this configuration.
Before you can register a database with the directory, you must do either one of the following two tasks:
Configure DNS discovery of Oracle Internet Directory on your network.

If DNS discovery is not configured on your network, then use Oracle Net Configuration Assistant to create an ldap.ora file for your Oracle home.
Your database initially uses the ldap.ora file to locate the correct Oracle Internet Directory server on your network. This configuration file contains the hostname, port number, and identity management realm information for your directory server.
Once database registration is complete, the realm is ascertained through the database DN stored in the database wallet.
