slapo-sssvlv (5oldap)


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




SLAPO-SSSVLV(5oldap)                                      SLAPO-SSSVLV(5oldap)

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


       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.

       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.
