For browsing huge amount of search results, Paged Results Control can be used on it own where the results can be returned in any order; but the Virtual List View (VLV) Control is aimed to bring back results which are sorted. In that sense, it must be used with Server-Side Sort (SSS) Control.
On the other hand, only attribute value is specified as greaterThanOrEqual as the follows:
VirtualListViewRequest ::= SEQUENCE {
....
greaterThanOrEqual [1] AssertionValue
},
}
Which attribute type (sn, cn or any) is this value associated with? That attribute type is specified and passed in another control -- Server-Side Sort Control. For this reason, VLV Control needs Sort Control.
