NAME         top

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

SYNOPSIS         top


DESCRIPTION         top

       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

       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.


       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.
