ca_openldap Chef Cookbook

This cookbook provides several recipes to perform the following actions: * configure a node to be an OpenLDAP server or OpenLDAP client, * import specific schemas, * create a DIT, * configure the PPolicy module * enable TLS support * populate the directory.

This cookbooks only supports OpenLDAP 2.4+, as it is based on the new on line configuration method.

Requirements

Platform:

RedHat and CentOS 6.0+ are the target platforms. Debian and Ubuntu are planned but currently not supported.

Cookbooks:

  • certificate (optional): ca_openldap supports the certificates and the related key file deployed with this cookbook.

Attributes

Common attributes

  • node['ca_openldap']['basedn'] - base DN of the directory (default: "dc=example,dc=com").
  • node['ca_openldap']['ldap_server'] - IP or hostname of the node which hosts the ldap server (default: "localhost").
  • node['ca_openldap']['default_ports']['ldap'] - Default LDAP port
  • node['ca_openldap']['ldap_port'] - port to connect to the LDAP server (used by the following recipes: client, dit, populate, ppolicy), must be consistent with node['ca_openldap']['default_ports'].

Server attributes

  • node['ca_openldap']['db_dir'] - Directory where the DB files are created (default: "/var/lib/ldap").
  • node['ca_openldap']['db_backend'] - Type of OpenLDAP database backend used. Available backends are HDB, BDB and MDB (default: "mdb").
  • node['ca_openldap']['rootdn'] - RootDN, relative to node['ca_openldap']['basedn'] (default: "cn=Manager")
  • node['ca_openldap']['rootpassword'] - Root Password, it is strongly recommended to modify the default value (default: "pa$$word")
  • node['ca_openldap']['slapd_sysconfig_file'] - Default location of the sysconfig file configuring LDAP daemon (default: "/etc/sysconfig/ldap")
  • node['ca_openldap']['ldap_log_level'] - Log level - see Slapd config for explanation of supported values (default: "-1")
  • node['ca_openldap']['default_ports']['ldap'] - Port of the 'clear' LDAP socket, used only when ca_openldap.tls.enable is to :no or :yes
  • node['ca_openldap']['defaut_ports']['ldaps'] - Port of the TLS socket, used only when ca_openldap.tls.enable is set to :yes or :exclusive
  • node['ca_openldap']['enable_ldapi'] - Enable LDAPI access (defaulttrue`).
  • node['ca_openldap']['slapd_listen_addresses'] - IP addresses or FQDN to listen to for LDAP/LDAPS accesses (default :['*']` - listen to all known addresses)
  • node['ca_openldap']['tls']['enable'] - Configure the TLS access support, accepted values are (default :exclusive):
    • :no TLS access is not allowed
    • :yes both clear and TLS accesses are allowed
    • :exclusive only TLS access is allowed (node['ca_openldap']['ldap_port'] shall be correctly set)
  • node['ca_openldap']['tls']['cacert_path'] - Path of the directory where the CA certificates are stored (default: "/etc/openldap/cacerts").
  • node['ca_openldap']['tls']['cert_file'] - Path of the node certificate (default: "/etc/openldap/certs/#{node['fqdn']}.pem").
  • node['ca_openldap']['tls']['key_file'] - Path of the private key related to the node certificate (default: "/etc/openldap/certs/#{node['fqdn']}.key").
  • node['ca_openldap']['general_configuration_options'] - Hash of options to merge into the general configuration file (cn=config.ldif). The special value ::delete:: implies that the option will be removed.
  • node['ca_openldap']['use_existing_certs_and_key'] - boolean configuring the support of certificates deployed with the certificate cookbook. When true, assume the CA certificate, the server certificate and its related key already exist under default directory set by the certificate cookbook (/etc/pki/tls for RHEL). Consequently, the following links are created:
    • node['ca_openldap']['tls']['cert_file']: points to the Server certificate (/etc/pki/tls/certs/<fqdn>.pem for RHEL).
    • node['ca_openldap']['tls']['cacert_path'] + "/" + cacert_hash + ".0": points to the CA certificate chain (/etc/pki/tls/certs/<hostname>-bundle.crt for RHEL), cacert_hash is the X509 hash of the CA certificate file. Additionally the key file (/etc/pki/tls/private/<fqdn>.key) is copied to node['ca_openldap']['tls']['key_file'].

ACL attributes

  • node['ca_openldap']['acls'] - ACLs, this is a ruby Array of the ACL to create, each line must comply with the OpenLDAP ACL syntax (default allows to read any attributes (except password) from any authenticated users and to write any attributes that belongs to the current user)

PPolicy attributes

  • node['ca_openldap']['ppolicy_default_config_dn'] - DN where the default ppolicy configuration is stored, relatively to the node['ca_openldap']['basedn'] (default: "cn=passwordDefault,ou=policies").
  • node['ca_openldap']['ppolicy_default_config'] - Default ppolicy configuration, supported attributes are defined by section "Object Class Attributes" in slapo-ppolicy(5) (check default value in attributes/default.rb)
  • node['ca_openldap']['ppolicy']['extra_ppolicies'] - Supplementary ppolicies to insert into the LDAP (default: []). Each entry shall be an hash with following symbols:
    • :dn - the partial DN of the ppolicy (relative to the base DN, e.g. "cn=myPPolicy,ou=policies")
    • :sn - the ppolicie's SN (e.g. "My password policy")
    • :attrs - an hash gathering ppolicie's config attributes (supported attributes are defined by section "Object Class Attributes" in slapo-ppolicy(5))

Schema attributes

  • node['ca_openldap']['schema_dir'] - Directory that should contain core schema files (and to which additional schemas should be copied) (default: "/etc/openldap/schema")
  • node['ca_openldap']['default_schemas'] - Default set of core LDAP schemas to load into LDAP database beside the core.ldif schema (default: %w(cosine nis inetorgperson))
  • node['ca_openldap']['schema_cookbook'] - Name of the cookbook which includes additional schemas to set up. Schemas are search as cookbook distribution files, under files/default/schemas/ (default: nil)
  • node['ca_openldap']['additional_schemas'] - List of schemas to import in the directory, the suffix ".schema" is added to each item of the list to build the complete file name (default: [])

DIT attributes

  • node['ca_openldap']['dit'] - JSON structure which defines the DIT, this attribute can be overriden by the ca_openldap/dit data bag item, see dit recipe for additional information.

Populate attributes

  • node['ca_openldap']['populate']['update_enable'] - when true, populate recipes performs an add or update entry rather than a simple add.
  • node['ca_openldap']['populate']['attributes_to_ignore'] - List of attributes not to update when update_enable is true.

Recipes

server

Sets up a slapd daemon on the current node.

This recipe performs the following actions: * install the relevant packages provided by the distribution * configure the base DN, root DN and root password according to the related attributes * enable if requested the TLS support (see dedicated section below) * set the base directory for the database backend files * set the slapd log level

acl

Configure Access Control List for a given server. Uses node.ca_openldap.acls as a list of ACLs to add.

client

Install the OpenLDAP client packages and configure access to an OpenLDAP Server.

This recipe depends on the common attributes and the node['ca_openldap']['use_existing_certs_and_key'] and node['ca_openldap']['tls']['cacert_path']attributes.

dit

Install the DIT based on a provided data bag item.

The DIT is defined by the ca_openldap/dit data bag item if it exists, otherwise by the node['ca_openldap']['dit'] attribute.

Each entry of the DIT is defined by an hash, where: * the key is the part of the DN relative to its parent * the value is a hash including the following keys: * "attrs": hash defining all attributes of the entry * "children": hash of the children entries

In the case of the data bag item, the DIT structure is found under the "dit" hash key.

Example of ca_openldap/dit data bag item:

    {
      "id": "dit",
      "dit": {
        "dc=example,dc=fr": {
          "attrs": {
            "objectClass": ["organization", "dcObject"],
            "description": "root of the directory",
            "o": "organization"
          },
          "children": {
            "ou=groups": {
              "attrs": {
                "objectClass": ["top", "organizationalUnit"]
              }
            },
            "ou=users": {
              "attrs": {
                "objectClass": ["top", "organizationalUnit"]
              }
            }
          }
        }
      }
    }

schemas

Install additional schemas provided as a file distribution (from another cookbook for example).

See the schema attributes above to configure this recipe.

Each provided schema file must comply with the standard schema format (have a look to the official schemas stored under /etc/openldap/schemas).

populate

Populate the directory based on a provided data bag item.

The data bag item is ca_openldap/populate. This data bag item shall defines the following entries: * a "base" which specify the DN to append to each consecutive branch DN * a list of branches (under "branches") . Each branch is defined by the following entries: * a "name" which defines the relative DN of the branch * a list of default classes (under "default_classes") to apply to each consecutive entry * a list of entries (under "entries"), each item of this list defines an entry to create or update in the directory under the related branch. An item is a hash where keys and values maps the LDAP attribute names and values.

Example of ca_openldap/populate data bag item:

    {
      "id": "populate",
      "base": "dc=example,dc=fr",
      "branches": [
        {
          "name": "ou=unixAccounts,ou=users",
          "default_classes": ["top", "posixAccount", "inetOrgPerson"],
          "entries": [
            {
              "dn": "uid=test1",
              "uidNumber": "12001",
              "uid": "test",
              "cn": "test",
              "gidNumber": "12001",
              "sn": "test user",
              "userPassword": "pa$$word",
              "homeDirectory": "/home/test"
            },
            {
              "dn": "uid=test2",
              "uidNumber": "12002",
              "uid": "test2",
              "cn": "test2",
              "gidNumber": "12002",
              "sn": "test user 2",
              "userPassword": "pa$$word",
              "homeDirectory": "/home/test2"
            }
          ]
        },
        {
          "name": "ou=groups",
          "default_classes": ["top", "posixGroup"],
          "entries": [
            {
              "dn": "cn=test1",
              "gidNumber": "12001",
              "memberUid": "test1"
            },
            {
              "dn": "cn=test2",
              "gidNumber": "12002",
              "memberUid": "test2"
            },
            {
              "dn": "cn=test",
              "gidNumber": "12000",
              "memberUid": ["test1", "test2"]
            }
          ]
        }
      ]
    }

ppolicy

Configure the PPolicy module.

Custom Resources

entry

This resource create or update an entry in LDAP server defined by following attributes: * node['ca_openldap']['ldap_server'] * node['ca_openldap']['ldap_port'] * node['ca_openldap']['rootdn'] and node['ca_openldap']['basedn'] * node['ca_openldap']['rootpassword']

Actions

  • create - Create or update an entry.

Properties

  • entry_dn - DN of the entry to create or update (resource name).
  • attributes - Entry attributes to set, this hash should not include the RDN attribute.

Example

  ca_opendalp_entry "uid=foo,ou=users,dc=example,dc=com" do
    attributes objectClass: ["top", "posixAccount", "inetOrgPerson"],
               uidNumber: "22001",
               cn: "Foo Bar",
               gidNumber: "22001",
               sn: "Foo Bar",
               userPassword: "pa$$word", # should be read from an encrytped data bag item !!
               homeDirectory: "/home/foo"
    end

TLS support

TLS support is managed by the server recipe and configured by the node['ca_openldap']['tls']['*'] attributes and node['ca_openldap']['use_existing_certs_and_key'] attribute. If node['ca_openldap']['use_existing_certs_and_key'] is set to false, the recipe assumes that the server and CA certificates and the server key are already provided by another cookbook. Note that openldap expects that CA certificate names should have their names of the form "xxxxx.0", where "xxxxx" is x509 hash of the certificate.

The x509 hash can be easily generated with the following command:

openssl x509 -noout -hash -in /path/to/certificate.pem

If node['ca_openldap']['use_existing_certs_and_key'] is set to true, the recipe assumes that the server and CA certificates were previously deployed by the certificate cookbook under the default locations. Consequently, the recipe creates two links which point to the server and CA certificates: * the server certificate link is created under the node['ca_openldap']['tls']['cert_file'] location, * the CA certification link is created in the node['ca_openldap']['tls']['cacert_path'] directory, with the proper name as explaine above.
Additionaly, the recipe copies the server key to the node['ca_openldap']['tls']['key_file'] location.

Take care to correctly set the node['ca_openldap']['ldap_port'] attribute to the LDAPS default port (636) when node['ca_openldap']['tls']['enable_tls'] is set to :exclusive, otherwise the dit and populate recipes will not work.
