Bug Description: If the substring index is configured for the group membership attribute ( member or uniqueMember ), the removal of a member from a large static group is pretty slow.
Fix Description: A solution to this issue would be to introduce a new index to track a membership atttribute index. In the interm, we add a check to healthcheck to inform the user of the implications of this configuration.
