About Importing Data from Active Directory Domain Services
Applies To: System Center Service Manager 2010 SP1
The System Center Service Manager 2010 Service Pack 1 (SP1) database contains information about your enterprise and is used by all the parts of your service management structure. You can use an Active Directory connector to add users, groups, printers, and computers (and only these object types) as configuration items into the Service Manager database.
Note
If the same user name exists in two different organizational units within the Active Directory domain, Service Manager cannot import both user accounts, and an event is logged in the System Center Operations Manager application log.
The users you import from Active Directory Domain Services (AD DS) can later be assigned to a user role, so that specific permissions are granted to specific users. However, users who do not exist in your organization’s Active Directory may need to be assigned to an activity. In this case, you must manually create a configuration item that contains all the necessary information about these users.
If you must later perform maintenance operations on the Service Manager database, you can temporarily disable the connector and suspend the importation of data. Later, you can resume the importation of data by re-enabling the connector.
When you import a large number of users from Active Directory Domain Services or from System Center Configuration Manager, CPU utilization might increase to 100 percent. You will notice this on one core of the CPU. For example, if you import 20,000 users, CPU utilization might remain high for 1.5 to 2 hours. You can mitigate this issue by creating connectors and importing the users into Service Manager before you deploy the product in your enterprise and by scheduling connector synchronization during off hours. Installing Service Manager on a computer that has a multi-core CPU also minimizes the impact of importing a large number of users.
