Well, I thought it was clear on the description of the evaluation:
To filter permissions as desired the plugin has to be the first one on the
permission_policy list and it works as follows:
1. If the blacklist is available and the permission being considered is on
the list the check_permission function returns False and the
permission
evaluation stops.
That means that the blacklist is always evaluated first.
Anyway, I'll add an explicit note saying that the blacklist always takes
precedence over the whitelist.
Greetings,
Sergio.
