Имя (Name)
slapo-valsort - Value Sorting overlay to slapd
Синопсис (Synopsis)
ETCDIR/slapd.conf
Описание (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.
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 {<weight>} 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 lber-encode(3) format,
the required value must conform to "{b}" syntax.
Конфигурация (Configuration)
These slapd.conf options apply to the Value Sorting overlay.
They should appear after the overlay directive.
valsort-attr <attribute> <baseDN> (<sort-method> | weighted
[<sort-method>])
Configure a sorting method for the specified attribute in
the subtree rooted at baseDN. The sort-method may be one
of alpha-ascend, alpha-descend, numeric-ascend, or
numeric-descend. If the special 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-method for an
attribute with a syntax other than Integer or
NumericString.
Примеры (Examples)
database mdb
suffix dc=example,dc=com
...
overlay valsort
valsort-attr member ou=groups,dc=example,dc=com alpha-ascend
To invoke ldapsearch(1) with the valsort control, the control
value must be set appropriately. The following octets represent
the desired "{b}" encoding:
0x30 0x03 0x01 0x01 0xff
The control can be sent from the command-line using the base64
encoding of the value:
ldapsearch -E 1.3.6.1.4.1.4203.666.5.14=::MAMBAf8=
