NAME
slapo-sssvlv - Server Side Sorting and Virtual List View overlay to
slapd
SYNOPSIS
/etc/ldap/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. Additional lim-
its may be configured as described below.
CONFIGURATION
These slapd.conf options apply to the SSSVLV overlay. They should ap-
pear 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 de-
fault 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.
