NAME
       slapo-valsort - Value Sorting overlay

SYNOPSIS
       /etc/openldap/slapd.conf

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 {} 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.

       These slapd.conf options apply to  the  Value  Sorting  overlay.   They
       should appear after the oovveerrllaayy directive.

       valsort-attr      (  | weighted [       method>])
              Configure  a  sorting  method for the specified attribute in the
              subtree rooted at baseDN.  The sort-method may be one of  aallpphhaa-
              aasscceenndd,  aallpphhaa-ddeesscceenndd,  nnuummeerriicc-aasscceenndd, or nnuummeerriicc-ddeesscceenndd.  If
              the special wweeiigghhtteedd 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 Numer-
              icString  syntax,  and it is an error to specify a numeric sort-
              method for an attribute with a  syntax  other  than  Integer  or
              NumericString.
