.SH NAME
|
|
slapo\-valsort \- Value Sorting overlay to slapd
|
|
.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 {<\fIweight\fP>}
|
|
in front of each value of the attribute for which weighted sorting is
|
|
desired. This weighting factor is stripped off and not returned in search
|
|
results unless the valsort control is specified (1.3.6.1.4.1.4203.666.5.14).
|
|
|
|
The valsort control requires a value consisting of a Sequence that contains
|
|
a boolean flag. The weighting factor is only returned if the boolean value is TRUE. In
|
|
.BR lber-encode (3)
|
|
format, the required value must conform to "{b}" syntax.
|
|
|
|
.SH CONFIGURATION
|
|
These
|
|
.I slapd.conf
|
|
options apply to the Value Sorting overlay.
|
|
They should appear after the
|
|
.B overlay
|
|
directive.
|
|
.TP
|
|
valsort\-attr <\fIattribute\fP> <\fIbaseDN\fP> (<\fIsort-method\fP> | weighted [<\fIsort-method\fP>])
|
|
Configure a sorting method for the specified
|
|
.I attribute
|
|
in the subtree rooted at
|
|
.IR baseDN .
|
|
The
|
|
.I 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
|
|
.I sort-method
|
|
may also be specified. It is an
|
|
error to specify an alphanumeric
|
|
.I sort-method
|
|
for an attribute with Integer
|
|
or NumericString syntax, and it is an error to specify a numeric
|
|
.I sort-method
|
|
for an attribute with a syntax other than Integer or NumericString.
|
|
.SH EXAMPLES
|
|
.LP
|
|
.nf
|
|
database mdb
|
|
suffix dc=example,dc=com
|
|
...
|
|
overlay valsort
|
|
valsort\-attr member ou=groups,dc=example,dc=com alpha\-ascend
|
|
.fi
|
|
|
|
To invoke
|
|
.BR ldapsearch (1)
|
|
with the valsort control, the control value must be set appropriately.
|
|
The following octets represent the desired "{b}" encoding:
|
|
.LP
|
|
.nf
|
|
0x30 0x03 0x01 0x01 0xff
|
|
.fi
|
|
|
|
The control can be sent from the command-line using the base64
|
|
encoding of the value:
|
|
.LP
|
|
.nf
|
|
ldapsearch \-E 1.3.6.1.4.1.4203.666.5.14=::MAMBAf8=
|
