Organization Units
Organization units (OU) are used to hierarchically group user and entities. Then you can get user or entities based on their OUs. When we click Administration/Organization units, we enter the related page:
Here, we can manage OUs (create, edit, delete, move) and members (add/remove).
In the left OU tree, we can right click to an OU (or left click to arrow at the right) to open context menu for OU operations. We can also add new members with the upper right button of members area.
This is actually a generic lookup modal and can be used to select any type of entity (see app/shared/common/lookup/common-lookup-modal.component).
Further information see ASP.NET Boilerplate Organization Unit Management Document.
