##Overview

This module installs (if necessary) and configures the System Security Services Daemon.

##Module Description

The System Security Services Daemon bridges the gap between local authentication requests and remote authentication providers. This module installs the required sssd packages and builds the sssd.conf configuration file. It will also enable the sssd service and ensure it is running.

Auto-creation of user home directories on first login via the PAM mkhomedir.so module may be enabled or disabled (defaults to disabled).

For SSH and Sudo integration with SSSD, this module works well with saz/ssh and trlinkin/nsswitch.

##Setup

###What sssd affects

• Packages
  • sssd
  • authconfig
  • oddjob-mkhomedir
  • libpam-runtime
  • libpam-sss
  • libnss-sss
• Files
  • sssd.conf
• Services
  • sssd daemon
• Execs
  • the authconfig or pam-auth-update commands are run to enable/disable SSSD functionality.

###Beginning with sssd

Install SSSD with a bare default config file:

 class {'::sssd': }

##Usage

Install SSSD with custom configuration:

class {'::sssd':
  config => {
    'sssd' => {
      'key'     => 'value',
      'domains' => ['MY_DOMAIN', 'LDAP',],
    },
    'domain/MY_DOMAIN' => {
      'key' => 'value',
    },
    'pam' => {
      'key' => 'value',
    },
  }
}

##Reference

###Parameters

• package_name: String. Name of the SSSD package to install.
• package_ensure: String. Ensure value to set for the SSSD package.
• service_name: String. Name of the SSSD service to manage.
• service_ensure: Variant[Enum['running','stopped'], Boolean]. Ensure value to set for the SSSD service.
• config_file: Stdlib::Absolutepath. Path to the SSSD config file.
• config: Hash. A hash of configuration options structured like the sssd.conf file. Array values will be joined into comma-separated lists.
• mkhomedir: Boolean. Enables auto-creation of home directories on user login.
• pam_mkhomedir_method: Enum['pam-auth-update', 'authconfig']. Set supported method for controlling SSSD configuration.
• pam_mkhomedir_file_path: Variant[Stdlib::Absolutepath, Undef]. Path to the PAM mkhomedir config file. Only used when pam_mkhomedir_method => pam-auth-update.
• cache_path: Stdlib::Absolutepath. Path to the SSSD cache files.
• clear_cache: Boolean. Enables clearing of the SSSD cache on configuration updates.
• required_packages: Hash. A Hash of package resources to additionally install with the core SSSD packages

For example:

class {'::sssd':
  config => {
    'sssd' => {
      'key1' => 'value1',
      'keyX' => [ 'valueY', 'valueZ' ],
    },
    'domain/LDAP' => {
      'key2' => 'value2',
    },
  }

or in hiera:

sssd::config:
  'sssd':
    key1: value1
    keyX:
      - valueY
      - valueZ
  'domain/LDAP':
    key2: value2

Will be represented in sssd.conf like this:

[sssd]
key1 = value1
keyX = valueY, valueZ

[domain/LDAP]
key2 = value2
