Enrolment

Hi people,
in Moodle 1.9 version we had a capability, moodle/course:view, that allows admins to manage the visibility of courses in one category for all user with a rol, student in this case, setting a exception in the category for student rol.
Now we have Moodle 2.6 and this capability has a different definition because the title is "View courses without participation", and if we set this exception has no effect, the users with student rol can see the courses where they are enroled anyway.

How can do this in the Moodle 2 version?

Thanks in advance
