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

22 This slapd.conf option applies to the NULL backend database. That is,
23 it must follow a "database null" line and come before any subsequent
24 "database" lines. Other database options are described in the
25 slapd.conf(5) manual page.
26
27 bind <on/off>
28 Allow binds as any DN in this backend's suffix, with any pass‐
29 word. The default is "off".
30
31 dosearch <on/off>
32 If enabled, a single entry will be returned on all search re‐
33 quests. The entry's DN will be the same as the database suffix.
34 The default is "off".

37 Here is a possible slapd.conf extract using the Null backend:
38
39 database null
40 suffix "cn=Nothing"
41 bind on

44 The null backend does not honor any of the access control semantics de‐
45 scribed in slapd.access(5).
