slapd-null5

Usage

Overview

The Null backend to slapd(8) is surely the most useful part of slapd:
- Searches return success but no entries.
- Compares return compareFalse.
- Updates return success (unless readonly is on) but do nothing.
- Binds other than as the rootdn fail unless the database option "bind on" is given.
- The slapadd(8) and slapcat(8) tools are equally exciting.
Inspired by the /dev/null device.

Configuration

This slapd.conf option applies to the NULL backend database. That is, it must follow a "database null" line and come before any subsequent "database" lines. Other database options are described in the slapd.conf(5) manual page.

bind <on/off>

Allow binds as any DN in this backend's suffix, with any password. The default is "off".

Examples

Here is a possible slapd.conf extract using the Null backend:

database null
suffix   "cn=Nothing"
bind     on

Access control

The null backend does not honor any of the access control semantics described in slapd.access(5).
