.SH NAME
|
|
slapo\-sssvlv \- Server Side Sorting and Virtual List View overlay to slapd
|
|
.SH SYNOPSIS
|
|
ETCDIR/slapd.conf
|
|
.SH 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
|
|
one sort request active at a time. Additional limits may be configured
|
|
as described below.
|
|
|
|
.SH CONFIGURATION
|
