``present`` will not update the attributes and their values if the

    entry is already present.

  **attributes** (dictionary, mandatory)

    Dictionary describing remaining attributes (except ``dn``). The keys in this

    dictionary should be the attribute names. The values should be either

    strings, for setting a single attribute value, or a list of strings if it is

    necessary to set multiple values for the same attribute.

**ldap_permissions** (list, optional, ``see below``)

  List of LDAP access rules to apply to base DN served by the LDAP server. The

  listed access control rules will *replace* all existing rules, and will be

  added in the same order they are listed in. Each item is a string that

  constitutes a single access control rule. The format should be the same as

  described in `OpenLDAP Administrator's Guide

  <http://www.openldap.org/doc/admin24/access-control.html#Access%20Control%20via%20Dynamic%20Configuration>`.

  Default value is:

  .. code-block:: yaml

**ldap_server_consumers** (list, optional, ``[]``)

  List of items describing additional login entries that should be created for

  services that want to be able to log-in into the LDAP server and consume the

  data present within. Each item should be a dictionary, with the following keys

  avaialable:

  - **name** (name of the service, mandatory, this will be used to construct the

    login entry DN in format of ``cn=NAME,ou=services,BASE_DN``)

  - **password** (password for the login entry, mandatory)

  - **state** (state of the service, optional, defaults to ``present``, this

    should be ``present`` or ``absent``, allowing for removal of old services)

**ldap_server_groups** (list, optional, ``[]``)

  List of groups that should be created in the LDAP directory. Each item should

  be a dictionary containing the following keys:

  - **name** (name of the group, mandatory, this will be used to construct the

    group DN in format of ``cn=NAME,ou=groups,BASE_DN``)

  - **state** (state of the group, optional, defaults to ``present``, this

    should be ``present`` or ``absent``, allowing for removal of old groups)

**ldap_server_domain** (string, optional, ``{{ ansible_domain }}``)

  Domain that should be used for constructing the base DN of default user LDAP

  database. This should be a sub-domain dedicated to organisation. The base DN

  will be constructed by putting all elements of the sub-domain as ``dc``

  entries (as per standard Debian convention). I.e. ``example.com`` would get

  transformed into ``dc=example,dc=com``.

**ldap_server_organization** (string, optional, ``Private``)

  Organization that should be specified in the base DN entry.

**ldap_server_log_level** (string, optional, ``256``)

  description and syntax.

**ldap_server_tls_certificate** (string, mandatory)

  X.509 certificate used for TLS for LDAP service. The file will be stored in

  directory ``/etc/ssl/certs/`` under name ``{{ ansible_fqdn }}_ldap.pem``.

**ldap_server_tls_key** (string, mandatory)

  Private key used for TLS for LDAP service. The file will be stored in

  directory ``/etc/ssl/private/`` under name ``{{ ansible_fqdn }}_ldap.key``.

XMPP Server

-----------

The ``xmpp_server`` role can be used for setting-up Prosody, an XMPP server, on

destination machine.

The role implements the following:

* Sets-up the Prosody apt repository.

* Deploys XMPP TLS private key and certificate.

* Installs Prosody.

* Configures Prosody.

* Configures firewall to allow incoming connections to the XMPP server.

Prosody is configured as follows:

* Modules enabled: roster, saslauth, tls, dialback, posix, private, vcard,

  version, uptime, time, ping, pep, register, admin_adhoc, announce, legacyauth.

* Self-registration is not allowed.

* TLS is configured. Legacy TLS is available on port 5223.

* Client-to-server communication requires encryption (TLS).

* Uses 2048-bit Diffie-Hellman parameters for relevant TLS ciphers for

  incoming connections.

* Authentication is done via LDAP. For setting the LDAP TLS truststore, see

  :ref:`LDAP Client <ldap_client>`.

* Internal storage is used.

* For each domain specified, a dedicated conference/multi-user chat (MUC)

  service is set-up, with FQDN set to ``conference.DOMAIN``.

* For each domain specified, a dedicated file proxy service will be set-up, with

  FQDN set to ``proxy.DOMAIN``.

Prosody expects a specific directory structure in LDAP when doing look-ups:

* Prosody will log-in to LDAP as user

  ``cn=prosody,ou=services,XMPP_LDAP_BASE_DN``.

* User entries are read from sub-tree (first-level only)

  ``ou=people,XMPP_LDAP_BASE_DN``. Query filter used for finding users is

  ``(&(mail=$user@$host)(memberOf=cn=xmpp,ou=groups,XMPP_LDAP_BASE_DN))``. This

  allows group-based granting of XMPP service to users.

LDIF Templates

~~~~~~~~~~~~~~

For adding user to a group, use::

  dn: cn=xmpp,ou=groups,BASE_DN

  changetype: modify

  add: uniqueMember

  uniqueMember: uid=USERNAME,ou=people,BASE_DN

Role dependencies

~~~~~~~~~~~~~~~~~

Depends on the following roles:

* **common**

* **backup_client**

Backups

~~~~~~~

If the backup for this role has been enabled, the following paths are backed-up:

**/var/lib/prosody/**

  Roster information, as well as undelivered (offline) messages for all XMPP

  users. Keep in mind that list of available users and their credentials are

  stored in the LDAP directory (which is backed-up via LDAP server role).

Parameters

~~~~~~~~~~

**xmpp_administrators** (list, mandatory)

  List of Prosody users that should be granted administrator privileges over

  Prosody. Each item is a string with value equal to XMPP user ID

  (i.e. ``john.doe@example.com``).

**xmpp_domains** (list, optional, ``{{ ansible_domain }}``)

  List of domains that are served by this Prosody instance. Each item is a

  string specifying a domain.

**xmpp_ldap_base_dn** (string, mandatory)

  Base DN on the LDAP server. A specific directory structure is expected under

  this entry (as explained above) in order to locate the available domains,

  users, aliases etc.

**xmpp_ldap_password** (string, mandatory)

  Password used for authenticating to the LDAP server.

**xmpp_ldap_server** (string, mandatory)

  Fully qualified domain name, hostname, or IP address of the LDAP server used

  for user authentication and listing.

**xmpp_prosody_package** (string, optional, ``prosody-0.10``)

  Name of Prosody package from the Prosody repositories to

  install. This makes it possible to easily test the latest Prosody or

**xmpp_tls_certificate** (string, mandatory)

  X.509 certificate used for TLS for XMPP service. The file will be stored in

  directory ``/etc/ssl/certs/`` under name ``{{ ansible_fqdn }}_xmpp.pem``.

**xmpp_tls_key** (string, mandatory)

  Private key used for TLS for XMPP service. The file will be stored in

  directory ``/etc/ssl/private/`` under name ``{{ ansible_fqdn }}_xmpp.key``.

Distribution compatibility

~~~~~~~~~~~~~~~~~~~~~~~~~~

Role is compatible with the following distributions:

- Debian 9 (Stretch)

Examples

~~~~~~~~

Here is an example configuration for setting-up XMPP server using Prosody:

.. code-block:: yaml

  ---

  xmpp_administrators:

    - john.doe@example.com

  xmpp_domains:

    - example.com

  xmpp_ldap_base_dn: dc=example,dc=com

  xmpp_ldap_password: xmpp

  xmpp_ldap_server: ldap.example.com

  # These are default key and certificate that generated during Prosody

  # installation. Possibly you want to deploy your own.

  xmpp_tls_key: "{{ lookup('file', '/etc/prosody/certs/localhost.key') }}"

  xmpp_tls_certificate: "{{ lookup('file', '/etc/prosody/certs/localhost.crt') }}"

Mail Server

-----------

.. warning::

   It may happen that the ``clamav-freshclam`` service hasn't finished

   downloading the virus database before the ``clamav-daemon`` and

   ``clamav-milter`` services are enabled during the initial run. If mail server

   is not operational, you may need to wait for a little while for download to

   finish, and then restart the ``clamav-daemon`` and ``clamav-milter``

   services.

The ``mail_server`` role can be used for setting-up a complete mail server

solution, which includes both SMTP and IMAP service, on destination machine.

Postfix is used SMTP, while Dovecot is used for IMAP.

The role implements the following:

* Installs rsync.

* Deploys IMAP/SMTP TLS private keys and certificates.

* Installs and configures Dovecot, Postfix, ClamAV, and ClamAV Milter.

* Purges Exim4 configuration (just in case).

* Sets-up aliases for the local recipients.

* Installs SWAKS (utility for testing SMTP servers).

* Sets-up the necessary directories and files under Postfix chroot.

* Configures firewall to allow incoming connections to the mail server. This

  includes set-up of redirection from TCP port 26 to TCP port 587 (alternate

  submission port), as well as redirection from TCP port 27 to TCP port 25

  (alternate SMTP port), useful as workaround for ISP/hotel blocks.

Deployed services are configured as follows:

* Both Postfix and Dovecot look-up available domains, users, and aliases in

  LDAP.

* Incoming and outgoing mail is scanned with ClamAV (via ClamAV

  Milter). Infected mails are rejected.

* Mail is stored in directory ``/var/MAIL_USER/DOMAIN/USER``, using ``Maildir``

  format.

* TLS is required for user log-ins for both SMTP and IMAP.

* Uses 2048-bit Diffie-Hellman parameters for relevant TLS ciphers for

  incoming connections.

* For user submission (SMTP), users must connect and authenticate over TCP

  port 587.

* Configures TLS versions and ciphers supported by Dovecot.

* Configures TLS versions and ciphers supported by Postfix on submission port

  (587). TLS configuration on port 25 is kept intact in order to maintain maximum

  interoperability with other servers.

* RBL's are used for combating spam (if any is specified in configuration, see

  below).

* Postfix is configured to deliver undeliverable bounces to postmaster. This

  helps with detecting misconfigured applications and servers.

Both Postfix and Dovecot expect a specific directory structure in LDAP when

doing look-ups:

* Postfix will log-in to LDAP as user

  ``cn=postfix,ou=services,MAIL_LDAP_BASE_DN``.

* Dovecot will log-in to LDAP as user

  ``cn=dovecot,ou=services,MAIL_LDAP_BASE_DN``.

* Domain entries need to be available as

  ``dc=DOMAIN,ou=domains,ou=mail,ou=services,MAIL_LDAP_BASE_DN``.

* Alias entries need to be available as

  ``cn=ALIAS,ou=aliases,ou=mail,ou=services,MAIL_LDAP_BASE_DN``.

* User entries are read from sub-tree (first-level only)

  ``ou=people,MAIL_LDAP_BASE_DN``. Query filter used for finding users is

  ``(&(mail=%s)(memberOf=cn=mail,ou=groups,MAIL_LDAP_BASE_DN))``. This allows

  group-based granting of mail services to users.
