Connections to external data systems
Connections to external data systems
External data systems supported out of the box
This section provides information on working with external data systems supported by Synchronization Service out of the box.
This section covers:
Working with Active Directory
This section describes how to create or modify a connection to Active Directory so that Synchronization Service could work with data in that data system.
To create a connection to Active Directory domain, you need to use Synchronization Service in conjunction with a special connector called Active Directory Connector. This connector is included in the Synchronization Service package.
The Active Directory Connector supports the following features:
Table 7: Supported features
Allows you to read and write data in the connected data system.
Delta processing mode
Allows you to process only the data that has changed in the connected data system since the last synchronization operation, thereby reducing the overall synchronization operation time.
Allows you to synchronize user passwords from an Active Directory domain to the connected data system.
The Active Directory Connector supports linked attributes existing in the Active Directory schema. Linked attributes allow you to establish associations between two objects.
Linked attributes exist in pairs, as follows:
- Forward link attribute. This is a linked attribute that exists on a source object (example: the member attribute on the Group object). Forward link attributes can be single-valued or multivalued.
- Back link attribute. This is a linked attribute that can be specified on a target object (example: the memberOf attribute on the User object). Back link attributes are multivalued and they must have a corresponding forward link attribute. Back link attributes are not stored in Active Directory. Rather, they are calculated based on the corresponding forward link attribute each time a query is issued.

Creating an Active Directory connection
To create a new connection
- In the Synchronization Service Administration Console, open the Connections tab.
- Click Add connection, and then use the following options:
- Connection name. Type a descriptive name for the connection.
- Use the specified connector. Select Active Directory Connector.
- Click Next.
- On the Specify connection settings page, use the following options:
- Any available domain controller in the specified domain. Allows you to connect to an available domain controller in the Active Directory domain you specify. In the Domain text box, type the fully qualified domain name of the domain to which you want to connect.
- Specified domain controller. Allows you to connect to a specific domain controller in a particular Active Directory domain. In the Domain controller text box, type the fully qualified domain name of the domain controller to which you want to connect.
- Active Directory forest. Allows you to connect to the Active Directory forest you specify in this option. When synchronizing data to or from a connected forest, Synchronization Service automatically selects the appropriate domain controllers in the forest to read and write data according to the synchronization scope configured for the connection.
- Secure Sockets Layer usage. Use this list to select one of the following:
- None. Allows you to connect without using Secure Sockets Layer (SSL).
- Use. Allows you to connect through SSL.
- Preferred. Allows you to attempt the connection through SSL first. If this connection attempt fails, the Synchronization Service tries to connect without using SSL.
- Access Active Directory using. Use this option to select one of the following:
- Synchronization Service account. Allows you to access the Active Directory domain in the security context of the account under which the Synchronization Service is running.
- Windows account. Allows you to access Active Directory in the security context of the account whose user name and password you specify below this option.
Click Finish to create a connection to Active Directory.
- Test Connection. Click this button to verify the specified connection settings.
