When you make a trustee assignment, you can grant object rights and/or property rights. Object rights apply to manipulation of the entire object, while property rights only apply to certain object properties.
Object rights are shown in the left-hand side of the NWAdmin Trustees dialog. A description of each right follows.
Supervisor includes all rights to the object and all of its specific properties.
Browse enables the trustee to see the object in the tree. It does not include the right to see an object's specific properties.
Create only applies when the target object is a container. The target in the example above is [Root], shown in the window's title bar. Create allows the trustee to create new objects below the container, and also includes the Browse right.
Delete allows the trustee to delete the target from the Directory.
Rename allows the trustee to change the name of the target.
