slapo-sssvlv(5)

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
   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.
