Editing OpenLDAP (section)

==Other modules==
Backends and overlays are the two most commonly used types of modules. Backends were typically built into the slapd binary, but they may also be built as dynamically loaded modules, and overlays are usually built as dynamic modules. In addition, slapd supports dynamic modules for implementing new LDAP syntaxes, matching rules, controls, and extended operations, as well as for implementing custom access control mechanisms and password hashing mechanisms.

OpenLDAP also supports SLAPI, the plugin architecture used by Sun and Netscape/Fedora/Red Hat. In current releases, the SLAPI framework is implemented inside a slapd overlay. While many plugins written for Sun/Netscape/Fedora/Red Hat are compatible with OpenLDAP, very few members of the OpenLDAP community use SLAPI.<ref name="slapi">{{cite web|url=https://www.openldap.org/software/man.cgi?query=slapd.plugin&apropos=0&sektion=0&manpath=OpenLDAP+2.6-Release&arch=default&format=html |title=OpenLDAP SLAPI plugins man page |access-date=25 October 2021}}</ref>
