Connect to LDAP Objects from PowerBuilder

This article demonstrates how to access LDAP objects from PowerBuilder using the CData ADO.NET Provider for LDAP.

The CData ADO.NET providers are easy-to-use, standards-based controls that can be used from any platform or development technology that supports Microsoft .NET, including PowerBuilder. This article shows how to use the CData ADO.NET Provider for LDAP in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for LDAP to perform reads and writes.

  1. In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:

    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.

  2. Add the DataGrid control from the .NET controls.
  3. Configure the columns of the DataGrid control. Below are several columns from the Account table: <DataGrid AutoGenerateColumns="False" Margin="13,249,12,14" Name="datagrid1" TabIndex="70" ItemsSource="{Binding}"> <DataGrid.Columns> <DataGridTextColumn x:Name="idColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" /> <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for LDAP assembly.

Connect the DataGrid

Once the visual elements have been configured, you can use standard ADO.NET objects like Connection, Command, and DataAdapter to populate a DataTable with the results of an SQL query:

System.Data.CData.LDAP.LDAPConnection conn conn = create System.Data.CData.LDAP.LDAPConnection(connectionString) System.Data.CData.LDAP.LDAPCommand comm comm = create System.Data.CData.LDAP.LDAPCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.LDAP.LDAPDataAdapter dataAdapter dataAdapter = create System.Data.CData.LDAP.LDAPDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

The code above can be used to bind data from the specified query to the DataGrid.
