Configuring the provisioning of memberships

Memberships, such as user accounts in groups, are saved in assignment tables in the One Identity Manager database. During provisioning of modified memberships, changes made in the target system may be overwritten. This behavior can occur under the following conditions:

  • Memberships are saved in the target system as an object property in list form (Example: List of user accounts in the Members property of an LDAP GroupOfNames).

  • Memberships can be modified in either of the connected systems.

  • A provisioning workflow and provisioning processes are set up.

If one membership in One Identity Manager changes, by default, the complete list of members is transferred to the target system. Therefore, memberships that were previously added to the target system are removed in the process and previously deleted memberships are added again.

To prevent this, provisioning can be configured such that only the modified membership is provisioned in the target system. The corresponding behavior is configured separately for each assignment table.

To allow separate provisioning of memberships

  1. In the Manager, select the LDAP | Basic configuration data | Target system types category.

  2. Select LDAP in the result list.

  3. Select the Configure tables for publishing task.

  4. Select the assignment tables that you want to set up for single provisioning. Multi-select is possible.

    • This option can only be enabled for assignment tables that have a base table with XDateSubItem or CCC_XDateSubItem column.

    • Assignment tables that are grouped together in a virtual schema property in the mapping must be marked identically (for example, LDAPAccountInLDAPGroup, LDAPGroupInLDAPGroup and LDAPMachineInLDAPGroup).

  5. Click Merge mode.

  6. Save the changes.

For each assignment table labeled like this, the changes made in One Identity Manager are saved in a separate table. During modification provisioning, the members list in the target system is compared to the entries in this table. This means that only modified memberships are provisioned and not the entire members list.

NOTE: The complete members list is updated by synchronization. During this process, objects with changes but incomplete provisioning are not handled. These objects are logged in the synchronization log.

You can restrict single provisioning of memberships with a condition. Once merge mode has been disabled for a table, the condition is deleted. Tables that have had the condition deleted or edited are marked with the following icon: . You can restore the original condition at any time.

To restore the default condition

  1. Select the auxiliary table for which you want to restore the condition.

  2. Right-click on the selected row and select the Restore original values context menu item.
  3. Save the changes.

For more detailed information about provisioning memberships, see the One Identity Manager Target System Synchronization Reference Guide.

Configuring single object synchronization

Changes made to individual objects in the target system can be immediately applied in the One Identity Manager database without having to start a full synchronization of the target system environment. Individual objects can only be synchronized if the object is already present in the One Identity Manager database. The changes are applied to the mapped object properties. If a member list is belongs to one of these properties, then the entries in the assignment table will also be updated. If the object is no longer present in the target system, then it is deleted from the One Identity Manager database.

Prerequisites
  • A synchronization step exists that can import the changes to the changed object into One Identity Manager.

  • The path to the base object of the synchronization is defined for the table that contains the changed object.

Single object synchronization is fully configured for synchronization projects created using the default project template. If you want to incorporate custom tables into this type of synchronization project, you must configure single object synchronization for these tables. For detailed information, see One Identity Manager Target System Synchronization Reference Guide.

To define the path to the base object for synchronization for a custom table

  1. In the Manager, select the LDAP | Basic configuration data | Target system types category.

  2. In the result list, select the LDAP target system type.

  3. Select the Assign synchronization tables task.

  4. In the Add assignments pane, assign the custom table for which you want to use single object synchronization.

  5. Save the changes.
  6. Select the Configure tables for publishing task.

  7. Select the custom table and enter the Root object path.

    Enter the path to the base object in the ObjectWalker notation of the VI.DB.

    Example:

  8. Save the changes.

Accelerating provisioning and single object synchronization

To smooth out spikes in data traffic, handling of processes for provisioning and single object synchronization can be distributed over several Job servers. This will also accelerate these processes.

NOTE: You should not implement load balancing for provisioning or single object synchronization on a permanent basis. Parallel processing of objects might result in dependencies not being resolved because referenced objects from another Job server have not been completely processed.

Once load balancing is no longer required, ensure that the synchronization server executes the provisioning processes and single object synchronization.

To configure load balancing

  1. Configure the server and declare it as a Job server in One Identity Manager.

    • Assign the LDAP connector server function to the Job server.

    All Job servers must access the same LDAP domain as the synchronization server for the respective base object.

  2. In the Synchronization Editor, assign a custom server function to the base object.

    This server function is used to identify all the Job servers being used for load balancing.

    If there is no custom server function for the base object, create a new one.

    For more information about editing base objects, see the One Identity Manager Target System Synchronization Reference Guide.

  3. In the Manager, assign this server function to all the Job servers that will be processing provisioning and single object synchronization for the base object.

    Only select those Job servers that have the same configuration as the base object's synchronization server.

Once all the processes have been handled, the synchronization server takes over provisioning and single object synchronization again.

To use the synchronization server without load balancing.

  • In the Synchronization Editor, remove the server function from the base object.

For detailed information about load balancing, see the One Identity Manager Target System Synchronization Reference Guide.

Executing synchronization

Synchronization is started using scheduled process plans. It is possible to start synchronization manually in the Synchronization Editor. You can simulate synchronization beforehand to estimate synchronization results and discover errors in the synchronization configuration. If synchronization was terminated unexpectedly, you must reset the start information to be able to restart synchronization.

If you want to specify the order in which target systems are synchronized, use the start up sequence to run synchronization. In a start up sequence, you can combine start up configurations from different synchronization projects and specify the order of execution. For detailed information about start up configurations, see the One Identity Manager Target System Synchronization Reference Guide.
