Organizational Units (OUs) are not used or supported by Umbrella.
Integration between Active Directory and Umbrella enables IP-to-user, IP-to-group and IP-to-computer mappings. The connector synchronizes user-to-group, computer-to-group and group-to-group memberships with the Umbrella Security Cloud, enabling you to create and enforce user, group and computer-based settings and view user, computer, and group-based reports.
The Virtual Appliance and the connector will import your Active Directory Users, Groups and Computers to provide these mappings. Other Active Directory objects, including Organization Units (OUs) are not imported.
You cannot apply specific content or security filtering based on OU's. We import only Users, Groups, and Computers. If you currently have OUs, we recommend creating an equivalent Group in your Active Directory configuration.
If you're interested in Umbrella AD integration supporting OU's, please submit a feature request to our support team at firstname.lastname@example.org
