Table of Contents

Overview

This module installs and manages SSSD. It allows you to set configuration options in sssd.conf through puppet / hiera.

WARNING

This module only supports sssd > 1.16.0

Use an older version of the module if you need lower version support

See REFERENCE.md for full API details

This is a SIMP module

This module is a component of the System Integrity Management Platform, a compliance-management framework built on Puppet.

If you find any issues, they can be submitted to our JIRA.

Please read our Contribution Guide.

This module is optimally designed for use within a larger SIMP ecosystem, but it can be used independently:

  • When included within the SIMP ecosystem, security compliance settings will be managed from the Puppet server.
  • In the future, all SIMP-managed security subsystems will be disabled by default and must be explicitly opted into by administrators. Please review simp/simp_options for details.

Module Description

This module installs, configures and manages SSSD. It is also cross compatible with simp/pki and simp/auditd.

It allows connection via krb5, ldap and local authentication.

simp/sssd also connects to autofs, nss, pac, pam, ssh, and sudo.

Setup

What simp sssd affects

Files managed by simp/sssd:

  • /etc/sssd/sssd.conf
  • /etc/init.d/sssd
  • (Optional) /etc/sssd/pki with simp/pki enabled

Services and operations managed or affected:

  • sssd (running)
  • nscd (stopped)

Packages installed:

  • sssd (latest by Default)
  • sssd-tools (optionally, latest by Default)
  • sssd-dbus (optionally, if ifp is included in sssd::services)

Usage

Beginning with SIMP SSSD

The following will install and manage the service for SSSD. It will configure the services defined in sssd::services (by default nss, pam, ssh and sudo.) If the host is joined to an IPA domain it will configure SSSD for the IPA domain. Otherwise the module does not create sssd domains or providers automatically. If the host is EL6 or EL7 the module will fail if you do not create a sssd domain.

include ::sssd

To enable integration with the existing SIMP PKI module, set the value of the PKI SIMP option to true:

This will use the simp pki certificate distribution mechanism and set the pki values accordingly in the ldap provider.

simp_options::pki: true

To enable integration with the simp auditd module, set the value of AUDITD SIMP option to true:

simp_options::auditd: true

Creating Domains and Providers

To create an SSSD domain you must instantiate a sssd::domain defined type and add the domain name to the array of domains in hiera:

In hiera:

sssd::domains: ['ldapusers', 'LOCAL']

Create a manifest:

sssd::domain { 'ldapusers':
  id_provider     => 'ldap',
  auth_provider   => 'krb5',
  access_provider => 'krb5',
  ...etc
}

sssd::domain { 'LOCAL':
  id_provider => 'local',
  ...etc
}

To include configuration options for the providers of the SSSD domain, you must instantiate the provider type with the same name as the domain it applies to. For example, to set options for the ldap and krb5 providers for the ldapusers domain defined above use the following:

sssd::provider::ldap { 'ldapusers':
  ldap_access_filter => 'memberOf=cn=allowedusers,ou=Groups,dc=example,dc=com',
  ldap_chpass_uri    => empty,
  ldap_access_order  => 'expire',
  ...etc
}

sssd::provider::krb5 { 'ldapusers':
  krb5_server   => 'my.kerberos.server',
  krb5_realm    => 'mykrbrealm',
  krb5_password => lookup('use_eyaml'),
  ...etc
}

More examples

Enabling Local Users

Using the LOCAL provider is supported for EL6 but has been deprecated by the vendor and is not recommended for use so is not documented here.

The following method works on EL7+ and is recommended by the vendor.

Add the following to your Hieradata:

---
sssd::enable_files_domain: true

More information can be found in sssd-local(5).

Using LDAP (Generic)

This should work with any general LDAP server, OpenLDAP, 389DS, etc...

sssd::domain { 'my_ldap':
  description       => 'LDAP Users',
  id_provider       => 'ldap',
  auth_provider     => 'ldap',
  chpass_provider   => 'ldap',
  access_provider   => 'ldap',
  sudo_provider     => 'ldap',
  autofs_provider   => 'ldap',
  min_id            => 500,
  cache_credentials => true
}

sssd::provider::ldap { 'my_ldap':
  ldap_default_authtok_type => 'password',
  ldap_user_gecos           => 'dn'
}
Using FreeIPA or Red Hat Directory Server

The sssd class, by default, configures SSSD for an IPA domain, when the host is joined to an IPA domain. If you want to manage this configuration yourself, set sssd::auto_add_ipa_domain to false. Then, configure the domain and ipa provider as follows

sssd::domain { 'my.domain':
  description       => "IPA Domain my.domain",
  id_provider       => 'ipa',
  auth_provider     => 'ipa',
  chpass_provider   => 'ipa',
  access_provider   => 'ipa',
  sudo_provider     => 'ipa',
  autofs_provider   => 'ipa',
}

sssd::provider::ipa { 'my.domain':
  ipa_domain => 'my.domain'
  ipa_server => [ 'ipaserver.my.domain' ]
}
Using Active Directory

For sssd to properly function with AD, you will need to join the system to the domain in whatever method suits your environment. There are several modules containing relevant tasks but this is technically outside of the realm of sssd so not included here.

$_my_ad_domain = 'test.domain'

# You may need to adjust these parameters for your exact environment but these
# should work for general use.

sssd::domain { $_my_ad_domain:
  access_provider           => 'ad',
  cache_credentials         => true,
  id_provider               => 'ad',
  realmd_tags               => 'manages-system joined-with-samba',
  case_sensitive            => true,
  max_id                    => 0,
  ignore_group_members      => true,
  use_fully_qualified_names => true
}

sssd::provider::ad { $_my_ad_domain:
  ad_domain                      => $_my_ad_domain,
  ad_servers                     => ["ad.${_my_ad_domain}"],
  ldap_id_mapping                => true,
  ldap_schema                    => 'ad',
  krb5_realm                     => upcase($_my_ad_domain),
  dyndns_update                  => true,
  default_shell                  => '/bin/bash',
  fallback_homedir               => '/home/%u@%d',
  krb5_store_password_if_offline => true
}

Using Services

The following services can be managed by simp/sssd.

  • autofs
  • ifp
  • nss
  • pac
  • pam
  • ssh
  • sudo

Adding a service to the array of services in sssd::services will configure it using the defaults from its module, sssd::service::{service name} . Use hiera to override the defaults.

  sssd::services: [ 'nss', 'pam', 'autofs']

The settings for the services have been known to change from one version of sssd to the next. To overcome this problem, a parameter, custom_options has been added. It accepts a hash of options for the service. It will ignore the other parameters in the service and use only these so you must add all options that differ from the system defaults.

  sssd::service::nss::custom_options:
    description: 'The nss section of the config file'
    filter_users:  'root'
    filter_groups: 'root'
    reconnection_retries:  3
    mymissingparam: 'value'
