Validate LDAP Objects with QuerySurge

QuerySurge is a smart data testing solution that automates data validation and testing. When paired with the CData JDBC Driver for LDAP, QuerySurge can work with live LDAP objects. This article walks through connecting to LDAP objects from QuerySurge.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live LDAP objects. When you issue complex SQL queries to LDAP, the driver pushes supported SQL operations, like filters and aggregations, directly to LDAP and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze LDAP objects using native data types.

Connecting to LDAP Objects in QuerySurge

To connect to live LDAP objects from QuerySurge, you need to deploy the JDBC Driver JAR file to your QuerySurge Agent(s) and add a new connection from the QuerySurge Admin view.

Deploy the JDBC Driver

1. Download the CData JDBC Driver for LDAP installer, unzip the package, and run the JAR file to install the driver.
2. Once the driver is installed, stop the Agent Service.
3. Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for LDAP\lib\) to your Agent(s) (QuerySurge_install_dir\agent\jdbc).
4. Restart the Agent Service.

For more information on deploying JDBC drivers for QuerySurge, refer to the QuerySurge Knowledge Base.

Configure a New Connection to LDAP

1. Log into QuerySurge and navigate to the Admin view.
2. Click Configuration -> Connections in the Administration Tree.
3. Click Add to create a new connection.
4. In the QuerySurge Connection Wizard, click Next.
5. Name the connection (e.g. CData JDBC Connection to LDAP).
6. Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
7. Set the Driver Class to cdata.jdbc.ldap.LDAPDriver and click Next.

8. Set the Connection URL using the necessary connection properties to authenticate with LDAP. Your Connection URL will look something like the following:

   jdbc:ldap:User=Domain\BobF;Password=bob123456;Server=10.0.1.1;Port=389;

   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.

   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.

9. Set the Test Query to enable the Test Connection button for the Connection (e.g. SELECT * FROM User LIMIT 1) and click Next.
10. Click Test Connection to ensure the connection is configured properly and click Save to add the connection.

Once the connection is added, you can write SQL queries against your LDAP objects in QuerySurge.

Compare LDAP Objects Queries with a QueryPair

With the connection configured, you can follow the steps below to compare querying LDAP objects with a QueryPair.

1. Select "Design Library" from the Design Menu
2. Click QueryPairs under QuerySurge Design
3. Click "Create New QueryPair"
4. Name the QueryPair and click Save
5. In either the Source or Target panes, select the connection created above (select the same connection to query LDAP twice or another connection to perform a comparison)
6. Write queries in the Editor for each pane, e.g. SELECT * FROM User
7. Click the "Design-Time Run" tab to execute the queries
8. When the query execution is finished, click "View Query Results" to see the LDAP objects returned by the query
