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.
