When Synchronizing data between two Active Directory domains, Synchronization Service uses the following ports to access domain controllers in the domains:
Port |
Protocol |
Type of traffic |
Direction of traffic |
53 |
TCP/UDP |
DNS |
Inbound |
88 |
TCP/UDP |
Kerberos |
Outbound |
389 |
TCP/UDP |
LDAP |
Outbound |
636 |
TCP |
LDAP over SSL (LDAPS) |
Outbound |
You can automatically synchronize user passwords from one Active Directory domain to the other by using Synchronization Service. The next procedure assumes that Synchronization Service is already connected to the source and target domains. For more information, see Creating an Active Directory connection.
To synchronize user passwords between two AD domains
Step 2 allows you to synchronize user passwords only once. If you want to synchronize all subsequent password changes on a permanent basis, complete step 3.
You can use Synchronization Service to synchronize SID history between user or group objects in two Active Directory domains. For example, you can synchronize SID history when migrating users from one Active Directory domain to the other.
Before you start synchronizing SID history, consider the following:
To synchronize SID history of users or groups
For instructions on how to install Capture Agent, see Managing Capture Agent.
For instructions on how to connect Synchronization Service to an Active Directory domain, see Creating an Active Directory connection.
If you use an updating synchronization step, ensure that user or group objects in the source domain are properly mapped to their counterparts in the target domain. For more information on mapping objects, see Mapping objects.
To read attribute values in the source domain and write them to the target domain, you can configure attribute modification rules in your sync workflow step. For detailed instructions, see Modifying attribute values by using rules.
This section explains how to create or modify a connection to an AD LDS (ADAM) instance so that Synchronization Service could work with data in that data system.
To create a connection to an AD LDS (ADAM) instance, you need to use Synchronization Service in conjunction with a special connector called AD LDS (ADAM) Connector. This connector is included in the Synchronization Service package.
The AD LDS (ADAM) Connector supports the following features:
Feature |
Supported |
Bidirectional synchronization Allows you to read and write data in the connected data system. |
Yes |
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. |
Yes |
Password synchronization Allows you to synchronize user passwords from an Active Directory domain to the connected data system. |
Yes |
