Use the CData ODBC Driver for LDAP in Microsoft Power Query

The CData ODBC Driver for LDAP enables you to link to LDAP objects in Microsoft Power Query, ensuring that you see any updates. This article details how to use the ODBC driver to import LDAP objects into Microsoft Power Query.

Connect to LDAP as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

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.

Import LDAP Objects

Follow the steps below to import LDAP objects using standard SQL:

1. From the ribbon in Excel, click Power Query -> From Other Data Sources -> From ODBC.

2. Enter the ODBC connection string. Below is a connection string using the default DSN created when you install the driver: Provider=MSDASQL.1;Persist Security Info=False;DSN=CData LDAP Source

3. Enter the SELECT statement to import data with. For example:

   SELECT Id, LogonCount FROM User

4. Enter credentials, if required, and click Connect. The results of the query are displayed in the Query Editor Preview. You can combine queries from other data sources or refine the data with Power Query formulas. To load the query to the worksheet, click the Close and Load button.
