NAME

6       slapo-sssvlv  -  Server  Side  Sorting and Virtual List View overlay to
7       slapd
8

SYNOPSIS

10       /etc/openldap/slapd.conf
11

DESCRIPTION

13       This overlay implements the LDAP Server Side Sorting (RFC2891)  control
14       as  well as the Virtual List View control. It also replaces the default
15       implementation of the LDAP PagedResults (RFC2696)  control,  to  ensure
16       that it works with Sorting. The overlay can be used with any backend or
17       globally for all backends.
18
19       Since a complete result set must be generated in memory before  sorting
20       can  be  performed, processing sort requests can have a large impact on
21       the server's memory use. As such, any connection is limited  to  having
22       only  a  limited  number  of sort requests active at a time. Additional
23       limits may be configured as described below.

CONFIGURATION

27       These slapd.conf options apply to the SSSVLV overlay.  They should  ap‐
28       pear after the overlay directive.
29
30       sssvlv-max <num>
31              Set  the  maximum  number  of  concurrent  sort requests allowed
32              across all connections. The default is one half of the number of
33              server threads.
34
35       sssvlv-maxkeys <num>
36              Set  the  maximum  number of keys allowed in a sort request. The
37              default is 5.
38
39       sssvlv-maxperconn <num>
40              Set the maximum number of concurrent paged search  requests  per
41              connection.  The default is 5. The number of concurrent requests
42              remains limited by sssvlv-max.
