• Root search
• For each root are recursively searched all its child nodes (based on the equality where the UID (identifier) of the parent node equals parent attribute of the child node).
• Synchronization is started for each tree element.

The roots of the tree are searched over the set of all accounts obtained from the source system. The reason why roots are not found using the search method on the end system is that their definition is in some cases too complex (the search criteria in the IC module are inadequate). Such a case is, for example, a situation where roots are all the elements (accounts) whose parent attribute are shown to themselves.

Root search is performed using the Groovy script in the synchronization configuration Definition of tree roots . This script runs over all system elements. If it returns Boolean.TRUE , then the element is root. If it returns Boolean.FALSE , it is not the root. The entry of this script is account (IcObject), an object of the element received from the IC module, so the names of the attributes are the names of the scheme attributes.

Example of a script addressing the situation described above :

// Name of the attribute in the scheme attributes, which contains the relation to the parent tree node
String PARENT_ATTR_NAME = "parent";
if(account){
 // Get value from parent attribute
 def parentValue = account.getAttributeByName(PARENT_ATTR_NAME).getValue();
 // Get value from ID attribute
 def uidValue = account.getAttributeByName("id").getValue();
 
 // Root is account, where is parent value equals with ID (externalId) value.
 if(parentValue != null && parentValue.equals(uidValue)){
     // We need clear value of parent attribute. In IDM has roots always parent = null.
     account.getAttributeByName(PARENT_ATTR_NAME).setValues(null);
     return Boolean.TRUE;
 }
}
 
return Boolean.FALSE;

Sometimes we need to synchronize all nodes from the source system under one node which already exists in the IdM.

For definition of that 'Super parent' node we cannot use:

• The transformation from the system (on 'parent' attribute), because we often use null value in the parent attribute as definition the root node.
• Selectbox on UI (configuration of the sync), because we sometimes want to use more 'Super parent' nodes (in case we have more roots and some of them should be under different 'Super parent').

Super parent node can be defined in the script for "Definition of tree roots". This script is defined on the sync configuration and we can set ID of super parent node to parent attribute.

// Name of the attribute in the scheme attributes, which contains the relation to the parent tree node
String PARENT_ATTR_NAME = "parent";
if(account){
 // Get value from parent attribute
 def parentValue = account.getAttributeByName(PARENT_ATTR_NAME).getValue();
 
 // Root is account, where is parent value is null
 if(parentValue == null){
     // Set default node
     account.getAttributeByName(PARENT_ATTR_NAME).setValues(["00a8aa04-667a-412e-bf3c-d892f2d9ca18"]);
     return Boolean.TRUE;
 }
}
 
return Boolean.FALSE;

Recalculation of automatic roles is skipped during sync. Recalculation of automatic roles can be (should be) correctly started after the end of the sync. This can be ensured by the property 'After end, start the automatic role recalculation' on the detail of sync configuration. Automatic roles are recalculated for synchronized tree nodes, where tree structure (parent node) was changed.
