I granted supervisory rights to one of my staff for a context and he
can now create users within that context. I then tried providing him
the necessary rights to modify the "Volume space restriction"
parameter of a volume by
- selecting the related volume of the context
- adding the user as a trustee
- enabling the SCRWA of the "Volume Space Restriction" parameter of
the volume.

This user still can not modify the space restrictions of the related

Any idea ?
