This illustration shows the page for editing the Parameter Details or the Predicate Details that apply to the Unique Certificate Constraint.
The Parameter Details section consists of a checkbox, labeled "Allow Multiple Certificates." The introductory text says a user can have multiple certificates of the same usage only if this checkbox is checked, as it is in this illustration.
The Predicate Details section includes two predicates, Type=="client" and Type=="server". A checkbox labeled "Allow Multiple Certificates" appears on each row, that is, for each of these predicates. Both corresponding checkboxes are empty, that is, not checked.
