Task 5: (Optional) Configure your Oracle home for directory usage
If you use Domain Name System (DNS) discovery (automatic domain name
lookup) to locate the directory on your network, then this step is not necessary. (See
Oracle Internet Directory Administrator's Guide for information about DNS server
discovery.) If you are not using DNS discovery, then you must use Oracle Net
Configuration Assistant to create an ldap.ora file for your Oracle home. This
configuration file specifies the directory host and port information, and the location
of the identity management realm so the database can connect to the directory. (See
"Starting Oracle Net Configuration Assistant"
To create an ldap.ora file for your Oracle home:
1.
2.
Note:
This default realm-wide setting can be overridden on a
database by setting the LDAP_DIRECTORY_ACCESS
initialization parameter. See Oracle Database Reference for more
information about this parameter.
If you are using SSL, then see Oracle Internet Directory
Administrator's Guide for information about setting up SSL with
two-way authentication for Oracle Internet Directory.
In the Oracle Net Configuration Assistant welcome page, choose Directory
Service Usage Configuration, and click Next.
Select one of the options on the Directory Usage Configuration page that is
appropriate for your environment. Then follow the prompts in the wizard and
refer to the online help to create an ldap.ora file for your Oracle home.
