.SH NAME
|
|
slapo-valsort \- Value Sorting overlay
|
|
.SH SYNOPSIS
|
|
ETCDIR/slapd.conf
|
|
.SH DESCRIPTION
|
|
The Value Sorting overlay can be used with a backend database to sort the
|
|
values of specific multi-valued attributes within a subtree. The sorting
|
|
occurs whenever the attributes are returned in a search response.
|
|
.LP
|
|
Sorting can be specified in ascending or descending order, using either
|
|
numeric or alphanumeric sort methods. Additionally, a "weighted" sort can
|
|
be specified, which uses a numeric weight prepended to the attribute values.
|
|
The weighted sort is always performed in ascending order, but may be combined
|
|
with the other methods for values that all have equal weights. The weight
|
|
is specified by prepending an integer weight
|
|
.B {<weight>}
|
|
in front of each value of the attribute for which weighted sorting is
|
|
desired. This weighting factor is stripped off and never returned in
|
|
search results.
|
|
|
|
.SH CONFIGURATION
|
|
These
|
|
.B slapd.conf
|
|
options apply to the Value Sorting overlay.
|
|
They should appear after the
|
|
.B overlay
|
|
directive and before any subsequent
|
|
.B database
|
|
directive.
|
|
.TP
|
|
.B valsort-attr <attribute> <baseDN> (<sort-method> | weighted [<sort-method>])
|
|
Configure a sorting method for the specified
|
|
.B attribute
|
|
in the subtree rooted at
|
|
.BR baseDN .
|
|
The
|
|
.B sort-method
|
|
may be one of
|
|
.BR alpha-ascend ,
|
|
.BR alpha-descend ,
|
|
.BR numeric-ascend ,
|
|
or
|
|
.BR numeric-descend .
|
|
If the special
|
|
.B weighted
|
|
method is specified, a secondary sort-method may also be specified. It is an
|
|
error to specify an alphanumeric sort-method for an attribute with Integer
|
|
or NumericString syntax, and it is an error to specify a numeric sort for
|
|
an attribute with a syntax other than Integer or NumericString.
