Replicate LDAP Objects to Multiple Databases

Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync integrates live LDAP objects into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote LDAP objects from Windows.

Configure Replication Destinations

Using CData Sync, you can replicate LDAP objects to any number of databases, both cloud-based and on-premises. To add a replication destination, navigate to the Connections tab.

For each destination database:

1. Click Add Connection.
2. Select a destination. In this article, we use SQLite.
3. Enter the necessary connection properties. To replicate LDAP to a SQLite database, enter a file path in the Data Source box.
4. Click Test Connection to ensure that the connection is configured properly.
5. Click Save Changes.

Configure the LDAP Connection

You can configure a connection to LDAP from the Connections tab. To add a connection to your LDAP account, navigate to the Connections tab.

1. Click Add Connection.
2. Select a source (LDAP).
3. Configure the connection properties.
   
   

   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 Connect to ensure that the connection is configured properly.
5. Click Save Changes.

Configure Replication Queries

CData Sync enables you to control replication with a point-and-click interface and with SQL queries. For each replication you wish to configure, navigate to the Jobs tab and click Add Job. Select the Source and Destination for your replication.

Replicate Entire Tables

To replicate an entire table, click Add Tables in the Tables section, choose the table(s) you wish to replicate, and click Add Selected Tables.

Customize Your Replication

You can use a SQL query to customize your replication. The REPLICATE statement is a high-level command that caches and maintains a table in your database. You can define any SELECT query supported by the LDAP API. To customize your replication, click Add Custom Query in the Tables section and define the Query Statement.

The statement below caches and incrementally updates a table of LDAP objects:

REPLICATE User;

You can specify a file containing the replication queries you want to use to update a particular database. Separate replication statements with semicolons. The following options are useful if you are replicating multiple LDAP accounts into the same database:

• Use a different table prefix in the REPLICATE SELECT statement:

  REPLICATE PROD_User SELECT * FROM User;

• Alternatively, use a different schema:

  REPLICATE PROD.User SELECT * FROM User;

Schedule Your Replication

In the Schedule section, you can schedule a job to run automatically, configuring the job to run after specified intervals ranging from once every 10 minutes to once every month.

Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your LDAP objects to disparate on-premises, cloud-based, and other databases.
