In 5.3.3.2. will be described how to create an one-way trust. Earlier releases had another default behaivior but the new one is already correctly documented in "5.3.1.". In 5.3.3.3. will be described how to verify a bidirectional trust, the given example "kvno -S cifs …" can only work if AD also trust IdM users (see also Bug 1305533).
Thank you for the report. We will investigate this bug.
I added steps how to verify a one-way trust to the book.
