slapd-null - Null backend to slapd
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.
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". dosearch <on/off> If enabled, a single entry will be returned on all search requests. The entry's DN will be the same as the database suffix. The default is "off".
Here is a possible slapd.conf extract using the Null backend: database null suffix "cn=Nothing" bind on
The null backend does not honor any of the access control semantics described in slapd.access(5).
