See the COPYRIGHT file. .\" $OpenLDAP$ .SH NAME slapo-cloak \- Attribute cloak overlay to slapd .SH SYNOPSIS ETCDIR/slapd.conf .SH DESCRIPTION The .B cloak overlay to .BR slapd (8) allows the server to hide specific attributes, unless explicitely requested by the client. This improve performance when a client requests all attributes and get a huge binary attribute that is of no interest for it. This behavior is disabled when the \fImanageDSAit\fP control (RFC 3296) is used. .SH CONFIGURATION The config directives that are specific to the .B cloak overlay must be prefixed by .BR cloak\- , to avoid potential conflicts with directives specific to the underlying database or to other stacked overlays. .TP .B overlay cloak This directive adds the cloak overlay to the current database, or to the frontend, if used before any database instantiation; see .BR slapd.conf (5) for details. .LP This .B slapd.conf configuration option is defined for the cloak overlay. It may have multiple occurrences, and it must appear after the .B overlay directive: .TP .B cloak-attr [] The value .B is the name of the attribute that will be cloaked. The optional .B restricts cloaking only to entries of the named .B . .SH EXAMPLE This example hide the .B jpegPhoto attribute. Add the following to slapd.conf: .LP .nf database # ... overlay cloak cloak-attr jpegPhoto .fi .LP and that slapd loads cloak.la, if compiled as a run-time module; .SH FILES .TP ETCDIR/slapd.conf default slapd configuration file .SH SEE ALSO .BR slapd.conf (5), .BR slapd (8). The .BR slapo-cloak (5) overlay supports dynamic configuration via .BR back-config . .SH ACKNOWLEDGEMENTS .P This module was originally written in 2008 by Emmanuel Dreyfus.
