For now, every getUser() and getGroup() method calls will validate the userFilter and the groupFilter if specified, as the filters are validated on the UI, as well, only the portal-ext.properties can specify invalid filters, so caching the filter validation errors instead of always validate them could save resources especially for bulk user or group imports.
