Build LDAP-Connected Web Apps in Servoy

Use Servoy Developer to easily connect to LDAP objects and build web apps with connectivity to live LDAP objects.

Servoy is a rapid application development and deployment platform. When paired with the CData JDBC Driver for LDAP, users can build LDAP-connected apps that work with live LDAP objects. This article describes how to connect to LDAP from Servoy and build a simple web app to display and search LDAP objects.

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 lets you work with LDAP objects using native data types.

Connect to LDAP in Servoy Developer

To build LDAP-connected apps, you need to first create a data provider in Servoy Developer using the CData JDBC Driver for LDAP.

  1. Install the JDBC Driver.
  2. Copy the JDBC Driver JAR file. (cdata.jdbc.ldap.jar) to the /application_server/drivers/ directory in the installation directory for Servoy.
  3. Open Servoy Developer.
  4. In the Solution Explorer, right-click Database Server (under Resources) and choose "Connect to existing database" -> "empty."
    1. Name the server.
    2. Click to show the advanced server settings.
      • Set the URL, for example: 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.

      • Select the Driver class you just copied, for example, cdata.jdbc.ldap.LDAPDriver

Build a LDAP-Connected Web App

Once you have configured the connection to LDAP in the Servoy Developer resources, you are ready to build apps with access to live LDAP objects.

Create a New Solution

  1. In the Server Explorer, right-click "All solutions" and select "Create new solution."
  2. Name the solution.
  3. Select the checkbox to include the "search" module.
  4. Click "Finish."

Create a New Form

Right-click "Forms" and select "Create new form."

  1. Name the form.
  2. Select a Datasource.
  3. Set the type (e.g., Simple) and click "Finish."

Add a Data Grid to the Form

  1. Drag a Data Grid component (from Servoy NG-Grids) onto the form.
  2. Drag a column component onto the Data Grid and set the "dataprovider" property for each column component to a column from the LDAP "table" (e.g., Id from the User table).

    Continue adding columns as desired.

Add Searching to the App

Note that the "svySearch" extension is required to add search functionality (included by default when you create a new solution). If you did not add the extension when you created the solution or you are modifying an existing solution, you can add the search module by right-clicking Modules (in the solution) and selecting "Add Module." Select "svySearch" and click "OK."

  1. Drag a Text Field component onto the Form.
  2. Right-click the Form and select "Open in Script Editor."
  3. Create a new variable (JavaScript) to hold the search value:
    var searchText = '';
    
  4. Back on the Form, in the Text Field properties:
    1. Set the "dataprovider" property to the Form variable you just created.
    2. Double-click to add a method for the onAction event.
    3. Click to create the method in "Form," name the method (e.g., onEnter), and click "Create private."
    4. Click "OK & Show."
  5. Add the following JavaScript to the JavaScript file to use the Servoy framework to implement searching bound data based on the text in the Text Field:
    var search = scopes.svySearch.createSimpleSearch(foundset).setSearchText(searchText);
    search.setSearchAllColumns();
    search.loadRecords(foundset);
    

Save and Launch the App

Save the form and JavaScript file, then click Run -> Launch NGClient to start the web app.
