Overview

This module installs and configures Realmd and joins a domain. It will also optionally control the Kerberos client and SSSD configuration files and the SSSD service.

Module Description

Realmd is a high-level tool for discovering and joining domains. It provides automatic base configuration of SSSD, nsswitch settings, and PAM configuration changes necessary for a Linux client to participate in an Active Directory domain.

This module will install the necessary Realmd packages and dependencies, configure Realmd, and join an Active Directory domain via one of two methods:

Username and password
Kerberos keytab file

It also optionally manages the contents of the Kerberos client configuration and SSSD configuration files.

Setup

What realmd affects

Packages
- Redhat Family
  - realmd
  - adcli
  - sssd
  - krb5-workstation
  - oddjob
  - oddjob-mkhomedir
- Debian Family
  - adcli
  - krb5-user
  - sssd
  - sssd-tools
  - samba-common-bin
  - samba
  - libpam-modules
  - libpam-sss
  - libnss-sss
Files
- /etc/realmd.conf
- /etc/sssd/sssd.conf
- /etc/krb5.conf
- /usr/share/pam-configs/realmd_mkhomedir (Debian Family)
Services
- sssd
Execs
- for username and password joins
  - the realm join command is run with supplied credentials
- for keytab joins
  - the kerberos config file (/etc/krb5.conf) will be placed on disk
  - the kinit command is run to obtain an initial TGT
  - the realm join command is run to join via keytab
- For Debian Family
  - triggers a pam-auth-update to activate the mkhomedir
- the SSSD config cache is forcibly removed on each config change to ensure cache is rebuilt

Setup Requirements

Keytabs
- this module does not manage keytabs -- the krb_keytab parameter is an absolute path to a keytab deployed in some way outside of this module

Beginning with realmd

Setup realmd and join an Active Directory domain via username and password:

class { '::realmd':
  domain               => 'example.com',
  domain_join_user     => 'user',
  domain_join_password => 'password',
}

Joining with a prepared computer account

Create the computer account by running adcli on any domain joined machine

new computer account: /usr/sbin/adcli preset-computer --domain example.com
or use an existing account: /usr/sbin/adcli reset-computer --domain example.com

Configure the realmd class

    class { '::realmd':
      domain             => $::domain,
      one_time_password  => 's3cure_pw', #optional, skip if you didn't specify it when running preset-computer# 
      #do not set domain_join_user
      #do not set krb_ticket_join
    }

Errors when running wio

Error: adcli join ... returned 3 instead of one of [0]

The account hasn't been prepared properly or the password is wrong

Usage

Set up Realmd, join an Active Directory domain via a keytab and fully configure SSSD:

class { '::realmd':
  domain             => $::domain,
  domain_join_user   => 'user',
  krb_ticket_join    => true,
  krb_keytab         => '/tmp/keytab',
  manage_sssd_config => true,
  sssd_config        => {
    'sssd' => {
      'domains'             => $::domain,
      'config_file_version' => '2',
      'services'            => 'nss,pam',
    },
    "domain/${::domain}" => {
      'ad_domain'                      => $::domain,
      'krb5_realm'                     => upcase($::domain),
      'realmd_tags'                    => 'manages-system joined-with-adcli',
      'cache_credentials'              => 'True',
      'id_provider'                    => 'ad',
      'access_provider'                => 'ad',
      'krb5_store_password_if_offline' => 'True',
      'default_shell'                  => '/bin/bash',
      'ldap_id_mapping'                => 'True',
      'fallback_homedir'               => '/home/%u',
    },
  },
}
