6 slapo-valsort \- Value Sorting overlay
10 The Value Sorting overlay can be used with a backend database to sort the
11 values of specific multi-valued attributes within a subtree. The sorting
12 occurs whenever the attributes are returned in a search response.
14 Sorting can be specified in ascending or descending order, using either
15 numeric or alphanumeric sort methods. Additionally, a "weighted" sort can
16 be specified, which uses a numeric weight prepended to the attribute values.
17 The weighted sort is always performed in ascending order, but may be combined
18 with the other methods for values that all have equal weights. The weight
19 is specified by prepending an integer weight {<\fIweight\fP>}
20 in front of each value of the attribute for which weighted sorting is
21 desired. This weighting factor is stripped off and never returned in
27 options apply to the Value Sorting overlay.
28 They should appear after the
30 directive and before any subsequent

52 error to specify an alphanumeric

55 or NumericString syntax, and it is an error to specify a numeric
57 for an attribute with a syntax other than Integer or NumericString.
