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. Addi-
tional 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.
