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