10 /etc/openldap/slapd.conf
11
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.

27 These slapd.conf options apply to the SSSVLV overlay. They should ap‐
28 pear after the overlay directive.
