Connect to LDAP Objects in CloverETL

Transfer LDAP objects using the visual workflow in the CloverETL data integration tool.

The CData JDBC Driver for LDAP enables you to use the data transformation components in CloverETL to execute create, read, update, and delete (CRUD) commands to LDAP objects. In this article, you will use the JDBC Driver for LDAP to set up a simple transfer into a flat file.

Connect to LDAP as a JDBC Data Source

  1. Create the connection to LDAP objects. In a new CloverETL graph, right-click the Connections node in the Outline pane and click Connections -> Create Connection. The Database Connection wizard is displayed.
  2. Click the plus icon to load a driver from a JAR. Browse to the lib subfolder of the installation directory and select the cdata.jdbc.ldap.jar file.
  3. Enter the JDBC URL. A typical JDBC URL is below: jdbc:ldap:User=Domain\BobF;Password=bob123456;Server=10.0.1.1;Port=389;

    To establish a connection, the following properties under the Authentication section must be provided:

    • Valid User and Password credentials (e.g., Domain\BobF or cn=Bob F,ou=Employees,dc=Domain).
    • Server information, including the IP or host name of the Server, as well as the Port.
    • BaseDN: This will limit the scope of LDAP searches to the height of the distinguished name provided.

      Note: Specifying a narrow BaseDN may greatly increase performance; for example, cn=users,dc=domain will only return results contained within cn=users and its children.

Query LDAP Objects with the DBInputTable Component

  1. Drag a DBInputTable from the Readers selection of the Palette onto the job flow and double-click it to open the configuration editor.
  2. In the DB connection property, select the LDAP JDBC data source from the drop-down menu.
  3. Enter the SQL query. For example: SELECT * FROM User

Write the Output of the Query to a UniversalDataWriter

  1. Drag a UniversalDataWriter from the Writers selection onto the jobflow.
  2. Double-click the UniversalDataWriter to open the configuration editor and add a file URL.
  3. Right-click the DBInputTable and then click Extract Metadata.
  4. Connect the output port of the DBInputTable to the UniversalDataWriter.
  5. In the resulting Select Metadata menu for the UniversalDataWriter, choose the User table. (You can also open this menu by right-clicking the input port for the UniversalDataWriter.)
  6. Click Run to write to the file.
