SLAPO-SSSVLV(5)		      File Formats Manual	       SLAPO-SSSVLV(5)

NAME
       slapo-sssvlv  -	Server	Side  Sorting and Virtual List View overlay to
       slapd

SYNOPSIS
       /usr/local/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. Additional
       limits 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
	      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.
