16.93. cdist-type__openldap_server(7)¶
16.93.1. NAME¶
cdist-type__openldap_server - Setup an openldap(4) server instance
16.93.2. DESCRIPTION¶
This type can be used to bootstrap an LDAP environment using openldap as slapd.
It bootstraps the LDAP server with sane defaults and creates and manages the base DN defined by suffix.
16.93.3. REQUIRED PARAMETERS¶
- manager-dn
- The rootdn to set up in the directory. E.g. cn=manager,dc=ungleich,dc=ch. See slapd.conf(5).
- manager-password
- The password for manager-dn in the directory. This will be used to connect to the LDAP server on the first slapd-url with the given manager-dn.
- manager-password-hash
The password for manager-dn in the directory. This should be valid for slapd.conf like {SSHA}qV+mCs3u8Q2sCmUXT4Ybw7MebHTASMyr. Generate e.g. with: slappasswd -s weneedgoodsecurity. See slappasswd(8C), slapd.conf(5). TODO: implement this: http://blog.adamsbros.org/2015/06/09/openldap-ssha-salted-hashes-by-hand/
to derive from the manager-password parameter and ensure idempotency (care with salts). At that point, manager-password-hash should be deprecated and ignored.- serverid
- The server for the directory. E.g. dc=ungleich,dc=ch. See slapd.conf(5).
- suffix
- The suffix for the directory. E.g. dc=ungleich,dc=ch. See slapd.conf(5).
16.93.4. REQUIRED MULTIPLE PARAMETERS¶
- slapd-url
- A URL for slapd to listen on. Pass once for each URL you want to support, e.g.: --slapd-url ldaps://my.fqdn/ --slapd-url ldap://my.fqdn/. The first instance that is passed will be used as the main URL to connect to this LDAP server See the -h flag in slapd(8C).
16.93.5. OPTIONAL PARAMETERS¶
- syncrepl-credentials
- Only has an effect if replicate is set; required in that case. This secret is shared amongst the hosts that will replicate the directory. Note that each replication server needs this secret and it is saved in plain text in the directory.
- syncrepl-searchbase
- Only has an effect if replicate is set; required in that case. The searchbase to use for replication. E.g. dc=ungleich,dc=ch. See slapd.conf(5).
- admin-email
- Passed to cdist-type__letsencrypt_cert; has otherwise no use. Required if using __letsencrypt_cert. Where to send Let's Encrypt emails like "certificate needs renewal".
- tls-cipher-suite
- Setting for TLSCipherSuite. Defaults to NORMAL in a Debian-like OS and HIGH:MEDIUM:+SSLv2 on FreeBSD. See slapd.conf(5).
- tls-cert
- If defined, __letsencrypt_cert is not used and this must be the path in the remote hosts to the PEM-encoded TLS certificate. Requires: tls-privkey and tls-ca. Permissions, existence and renewal of these files are left up to the type's user.
- tls-privkey
- Required if tls-cert is defined. Path in the remote hosts to the PEM-encoded private key file.
- tls-ca
- Required if tls-cert is defined. Path in the remote hosts to the PEM-encoded CA certificate file.
16.93.6. OPTIONAL MULTIPLE PARAMETERS¶
- syncrepl-host
- Only has an effect if replicate is set; required in that case. Set once per host that will replicate the directory.
- module
- LDAP module to load. See slapd.conf(5). Default value is OS-dependent, see manifest.
- schema
- Name of LDAP schema to load. Must be the name without extension of a .schema file in slapd's schema directory (usually /etc/slapd/schema or /usr/local/etc/openldap/schema). Example value: inetorgperson The type user must ensure that the schema file is deployed. This defaults to a sensible subset, for details see the type definition.
- description
- The description of the base DN passed in the suffix parameter. Defaults to Managed by cdist, do not edit manually.
16.93.7. BOOLEAN PARAMETERS¶
- staging
- Passed to cdist-type__letsencrypt_cert; has otherwise no use. Obtain a test certificate from a staging server.
- replicate
- Whether to setup replication or not. If present syncrepl-credentials and syncrepl-host are also required.
16.93.8. EXAMPLES¶
# Example of a simple server with manual certificate management.
pki_prefix="/usr/local/etc/pki/realms/ldap.camilion.cloud"
__openldap_server \
--manager-dn 'cn=manager,dc=camilion,dc=cloud' \
--manager-password "foo" \
--manager-password-hash '{SSHA}foo' \
--serverid 0 \
--suffix 'dc=camilion,dc=cloud' \
--slapd-url 'ldaps://ldap.camilion.cloud' \
--tls-cert "${pki_prefix}/default.crt" \
--tls-privkey "${pki_prefix}/default.key" \
--tls-ca "${pki_prefix}/CA.crt"
# The created basedn looks as follows:
#
# dn: dc=camilion,dc=cloud
# objectClass: top
# objectClass: dcObject
# objectClass: organization
# o: Managed by cdist, do not edit manually.
# dc: camilion
#
# Do not change it manually, the type will overwrite your changes.
#
# Changing to a replicated setup is a simple change to something like:
#
# Example for multiple servers with replication and automatic
# Let's Encrypt certificate management through certbot.
