SLAPD-SHELL

NAME

slapd-shell - Shell backend to slapd

SYNOPSIS

/etc/openldap/slapd.conf

DESCRIPTION

The Shell backend to slapd(8) executes external programs to implement operations, and is designed to make it easy to tie an existing database to the slapd front-end.

This backend is is primarily intended to be used in prototypes.

WARNING

The abandon shell command has been removed since OpenLDAP 2.1.

CONFIGURATION

These slapd.conf options apply to the SHELL backend database. That is, they must follow a "database shell" line and come before any subsequent "backend" or "database" lines. Other database options are described in the slapd.conf(5) manual page.

These options specify the pathname and arguments of the program to execute in response to the given LDAP operation. Each option is followed by the input lines that the program receives:

add <pathname> <argument>...

ADD
msgid: <message id>
<repeat { "suffix:" <database suffix DN> }>
<entry in LDIF format>

bind <pathname> <argument>...

BIND
msgid: <message id>
<repeat { "suffix:" <database suffix DN> }>
dn: <DN>
method: <method number>
credlen: <length of <credentials>>
cred: <credentials>

compare <pathname> <argument>...

COMPARE
msgid: <message id>
<repeat { "suffix:" <database suffix DN> }>
dn: <DN>
<attribute>: <value>

delete <pathname> <argument>...

DELETE
msgid: <message id>
<repeat { "suffix:" <database suffix DN> }>
dn: <DN>

modify <pathname> <argument>...

MODIFY
msgid: <message id>
<repeat { "suffix:" <database suffix DN> }>
dn: <DN>
<repeat {
    <"add"/"delete"/"replace">: <attribute>
    <repeat { <attribute>: <value> }>
    -
}>

modrdn <pathname> <argument>...

MODRDN
msgid: <message id>
<repeat { "suffix:" <database suffix DN> }>
dn: <DN>
newrdn: <new RDN>
deleteoldrdn: <0 or 1>
<if new superior is specified: "newSuperior: <DN>">

search <pathname> <argument>...

SEARCH
msgid: <message id>
<repeat { "suffix:" <database suffix DN> }>
base: <base DN>
scope: <0-2, see ldap.h>
deref: <0-3, see ldap.h>
sizelimit: <size limit>
timelimit: <time limit>
filter: <filter>
attrsonly: <0 or 1>
attrs: <"all" or space-separated attribute list>

unbind <pathname> <argument>...

UNBIND
msgid: <message id>
<repeat { "suffix:" <database suffix DN> }>
dn: <bound DN>

Note that you need only supply configuration lines for those commands you want the backend to handle. Operations for which a command is not supplied will be refused with an "unwilling to perform" error.

The commands - except unbind - should output:

RESULT
code: <integer>
matched: <matched DN>
info: <text>

where only RESULT is mandatory. The search RESULT should be preceded by the entries in LDIF format, each entry followed by a blank line. Lines starting with `#' or `DEBUG:' are ignored.

EXAMPLE

There is an example search script in the slapd/back-shell/ directory in the OpenLDAP source tree.

LIMITATIONS

The shell backend does not support threaded environments. When using the shell backend, slapd(8) should be built --without-threads.
