NAME
       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. Additional
       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.
