LDAP JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with LDAP directory services!



Create a simple Mule Application that uses HTTP and SQL with the CData JDBC Driver for LDAP to create a JSON endpoint for LDAP objects.

The CData JDBC Driver for LDAP connects LDAP objects to Mule applications enabling read , write, update, and delete functionality with familiar SQL queries. The JDBC Driver allows users to easily create Mule applications to backup, transform, report, and analyze LDAP objects.

This article demonstrates how to use the CData JDBC Driver for LDAP inside of a Mule project to create a Web interface for LDAP objects. The application created allows you to request LDAP objects using an HTTP request and have the results returned as JSON. The exact same procedure outlined below can be used with any CData JDBC Driver to create a Web interface for the 200+ available data sources.

  1. Create a new Mule Project in Anypoint Studio.
  2. Add an HTTP Connector to the Message Flow.
  3. Configure the address for the HTTP Connector.
  4. Add a Database Select Connector to the same flow, after the HTTP Connector.
  5. Create a new Connection (or edit an existing one) and configure the properties.
    • Set Connection to "Generic Connection"
    • Select the CData JDBC Driver JAR file in the Required Libraries section (e.g. cdata.jdbc.ldap.jar).
    • Set the URL to the connection string for LDAP

      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.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the LDAP JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.ldap.jar

      Fill in the connection properties and copy the connection string to the clipboard.

    • Set the Driver class name to cdata.jdbc.ldap.LDAPDriver.
    • Click Test Connection.
  6. Set the SQL Query Text to a SQL query to request LDAP objects. For example: SELECT Id, LogonCount FROM User
  7. Add a Transform Message Component to the flow.
  8. Set the Output script to the following to convert the payload to JSON:
    %dw 2.0
    output application/json
    ---
    payload
            
  9. To view your LDAP objects, navigate to the address you configured for the HTTP Connector (localhost:8081 by default): http://localhost:8081. The LDAP objects is available as JSON in your Web browser and any other tools capable of consuming JSON endpoints.

At this point, you have a simple Web interface for working with LDAP objects (as JSON data) in custom apps and a wide variety of BI, reporting, and ETL tools. Download a free, 30 day trial of the JDBC Driver for LDAP and see the CData difference in your Mule Applications today.
