Connect to LDAP Objects as a Federated Tables in MySQL

Use the CData Cloud Hub to set up federated tables for LDAP objects in MySQL .

You can use the CData Cloud Hub to set up federated tables in MySQL for LDAP objects. The Cloud Hub provides a MySQL interface for LDAP: After configuring a virtual MySQL database for LDAP, you can create a server and tables using the FEDERATED Storage Engine in MySQL. You can then work with LDAP objects just as you would local MySQL tables.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for LDAP, allowing you to easily query live LDAP objects alongside existing MySQL data — all without replicating the data. Using optimized data processing out of the box, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc) directly to LDAP, leveraging server-side processing to quickly return LDAP objects.

Create a Virtual MySQL Database for LDAP Objects

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "LDAP" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to LDAP.

    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.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to LDAP objects from any MySQL client.

Create a FEDERATED Server and Tables for LDAP Objects

After you have configured and started the service, create a FEDERATED server to simplify the process of creating FEDERATED tables:

Create a FEDERATED Server

The following statement will create a FEDERATED server based on the Cloud Hub. Note that the username and password of the FEDERATED server must match a user account you defined on the Cloud Hub.

CREATE SERVER fedLDAP
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'cloud_hub_user', PASSWORD 'cloud_hub_passwd', HOST 'myinstance.cdatacloud.net', PORT 3306, DATABASE 'ldapdb');

Create a FEDERATED Table

To create a FEDERATED table using our newly created server, use the CONNECTION keyword and pass the name of the FEDERATED server and the remote table (User). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_user (
  ...,
  id  TYPE(LEN),
  logoncount  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=utf8
CONNECTION='fedLDAP/User';

NOTE: The table schema for the FEDERATED table must match the remote table schema exactly. You can always connect directly to the Cloud Hub using any MySQL client and run SHOW COLUMNS FROM User to get the table schema.

Execute Queries

You can now execute queries to the LDAP FEDERATED tables from any tool that can connect to MySQL, which is particularly useful if you need to JOIN data from a local table with data from LDAP. Refer to the following example:

SELECT 
  fed_user.id, 
  local_table.custom_field 
FROM 
  local_table 
JOIN 
  fed_user 
ON 
  local_table.foreign_id = fed_user.id;
