.`dsctl healthcheck` now warns about creating a substring index on the membership attribute An entry that contains a membership attribute is usually a group with many members. When changing the value set, substring index is very expensive even for a minor change like deleting a single member. Now, when you add the substring index type, `dsctl healthcheck` warns about possible high cost of substring index on membership attributes and displays the following error message: `DSMOLE0002`. If the substring index is configured for a membership attribute, the removal of a member from the large group can be slow.
