Active Directory JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Active Directory Users, Groups, Roles, Contacts, and more!



Use the Remoting features of the Active Directory JDBC Driver to create a PostgreSQL entry-point for data access.

There are a vast number of PostgreSQL clients available on the Internet. From standard Drivers to BI and Analytics tools, PostgreSQL is a popular interface for data access. Using our JDBC Drivers, you can now create PostgreSQL entry-points that you can connect to from any standard client.

To access Active Directory data as a PostgreSQL database, use the CData JDBC Driver for Active Directory and a JDBC foreign data wrapper (FDW). In this article, we compile the FDW, install it, and query Active Directory data from PostgreSQL Server.

Connect to Active Directory Data as a JDBC Data Source

To connect to Active Directory as a JDBC data source, you will need the following:

  • Driver JAR path: The JAR is located in the lib subfolder of the installation directory.
  • Driver class: cdata.jdbc.activedirectory.ActiveDirectoryDriver

  • JDBC URL: The URL must start with "jdbc:activedirectory:" and can include any of the connection properties in name-value pairs separated with semicolons.

    To establish a connection, set the following properties:

    • 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 Active Directory JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.activedirectory.jar

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

    A typical JDBC URL is below:

    jdbc:activedirectory:User=cn=Bob F,ou=Employees,dc=Domain;Password=bob123;Server=10.0.1.2;Port=389;

Build the JDBC Foreign Data Wrapper

The Foreign Data Wrapper can be installed as an extension to PostgreSQL, without recompiling PostgreSQL. The jdbc2_fdw extension is used as an example (downloadable here).

  1. Add a symlink from the shared object for your version of the JRE to /usr/lib/libjvm.so. For example: ln -s /usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server/libjvm.so /usr/lib/libjvm.so
  2. Start the build: make install USE_PGXS=1

Query Active Directory Data as a PostgreSQL Database

After you have installed the extension, follow the steps below to start executing queries to Active Directory data:

  1. Log into your database.
  2. Load the extension for the database: CREATE EXTENSION jdbc2_fdw;
  3. Create a server object for Active Directory: CREATE SERVER ActiveDirectory FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS ( drivername 'cdata.jdbc.activedirectory.ActiveDirectoryDriver', url 'jdbc:activedirectory:User=cn=Bob F,ou=Employees,dc=Domain;Password=bob123;Server=10.0.1.2;Port=389;', querytimeout '15', jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.activedirectory.jar');
  4. Create a user mapping for the username and password of a user known to the MySQL daemon. CREATE USER MAPPING for postgres SERVER ActiveDirectory OPTIONS ( username 'admin', password 'test');
  5. Create a foreign table in your local database: postgres=# CREATE FOREIGN TABLE user ( user_id text, user_Id text, user_LogonCount numeric) SERVER ActiveDirectory OPTIONS ( table_name 'user');
You can now execute read/write commands to Active Directory: postgres=# SELECT * FROM user;
