slapo-sssvlv - Server Side Sorting and Virtual List View overlay to slapd SYNOPSIS
/etc/openldap/slapd.conf DESCRIPTION
This overlay implements the LDAP Server Side Sorting (RFC2891) control as well as the Virtual List View control. It also replaces the default implementation of the LDAP PagedResults (RFC2696) control, to ensure that it works with Sorting. The overlay can be used with any backend or globally for all backends. Since a complete result set must be generated in memory before sorting can be performed, processing sort requests can have a large impact on the server's memory use. As such, any connection is limited to having only a limited number of sort requests active at a time. Addi- tional limits may be configured as described below. CONFIGURATION
These slapd.conf options apply to the SSSVLV overlay. They should appear after the overlay directive. sssvlv-max <num> Set the maximum number of concurrent sort requests allowed across all connections. The default is one half of the number of server threads. sssvlv-maxkeys <num> Set the maximum number of keys allowed in a sort request. The default is 5. sssvlv-maxperconn <num> Set the maximum number of concurrent paged search requests per connection. The default is 5. The number of concurrent requests remains limited by sssvlv-max.

slapo-valsort - Value Sorting overlay to slapd 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 {<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. 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.
