It also replaces the default 14implementation of the LDAP PagedResults (RFC2696) control, to ensure 15that it works with Sorting. The overlay can be used with any backend 16or globally for all backends. 17 18Since a complete result set must be generated in memory before sorting can 19be performed, processing sort requests can have a large impact on the 20server's memory use. As such, any connection is limited to having only 21a limited number of sort requests active at a time. Additional limits may 22be configured as described below. 23 24.SH CONFIGURATION 25These 26.B slapd.conf 27options apply to the SSSVLV overlay. 28They should appear after the 29.B overlay 30directive. 31.TP 32.B sssvlv\-max <num> 33Set the maximum number of concurrent sort requests allowed across all 34connections. The default is one half of the number of server threads. 35.TP 36.B sssvlv\-maxkeys <num> 37Set the maximum number of keys allowed in a sort request. The default is 5. 38.TP 39.B sssvlv\-maxperconn <num> 40Set the maximum number of concurrent paged search requests per connection. The default is 5.
