slapo-valsort - Value Sorting overlay to slapd
ETCDIR/slapd.conf
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.
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.

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=
