Script Repository

Update allowed values property pattern based on group members

September 04, 2023 Views: 1092

The script updates the list of values allowed for a DN syntax property by a property pattern with members of groups. To run the script, create a scheduled task configured for the Domain-DNS object type and add a managed domain to the Activity Scope. The domain will only be used to trigger execution of the scheduled task. The search criteria are specified in the script.

Parameters

  • $groupDNs - Specifies distinguished names (DNs) of the groups whose members will be set as allowed property values.
  • $isPropertyRequired - Specifies whether the property should be set as required in the property pattern.
  • $patternName - Specifies the distinguished name (DN) of the property pattern to update.
  • $propertyName - Specifies the name of the property for which the list of allowed values will be updated in a property pattern.
