ipareplica role

Description

This role allows to configure a new IPA server that is a replica of the server. Once it has been created it is an exact copy of the original IPA server and is an equal master. Changes made to any master are automatically replicated to other masters.

This can be done in differnt ways using auto-discovery of the servers, domain and other settings or by specifying them.

Usage

Example inventory file with fixed principal using auto-discovery with DNS records:

[ipareplicas]
ipareplica1.example.com
ipareplica2.example.com

[ipareplicas:vars]
ipaadmin_principal=admin

Example playbook to setup the IPA client(s) using principal from inventory file and password from an Ansible Vault file:

- name: Playbook to configure IPA replicas
  hosts: ipareplicas
  become: true
  vars_files:
  - playbook_sensitive_data.yml

  roles:
  - role: ipareplica
    state: present

Example playbook to unconfigure the IPA client(s) using principal and password from inventory file:

- name: Playbook to unconfigure IPA replicas
  hosts: ipareplicas
  become: true

  roles:
  - role: ipareplica
    state: absent

Example inventory file with fixed server, principal, password and domain:

[ipaserver]
ipaserver.example.com

[ipareplicas]
ipareplica1.example.com
ipareplica2.example.com

[ipareplicas:vars]
ipaclient_domain=example.com
ipaadmin_principal=admin
ipaadmin_password=MySecretPassword123
ipadm_password=MySecretPassword456

Example playbook to setup the IPA client(s) using principal and password from inventory file:

- name: Playbook to configure IPA replicas with username/password
  hosts: ipareplicas
  become: true

  roles:
  - role: ipareplica
    state: present

Variables

ipaserver - Group with IPA server hostname. (list of strings, optional)

ipaclients - Group of IPA client hostnames. (list of strings)

ipaadmin_keytab - The path to the admin keytab used for alternative authentication. (string, optional)

ipaadmin_principal - The authorized kerberos principal used to join the IPA realm. (string, optional)

ipaadmin_password - The password for the kerberos principal. (string, optional)

ipaclient_domain - The primary DNS domain of an existing IPA deployment. (string, optional)

ipaclient_realm - The Kerberos realm of an existing IPA deployment. (string, optional)

ipaclient_keytab - The path to a backed-up host keytab from previous enrollment. (string, optional)

ipaclient_force_join - Set force_join to yes to join the host even if it is already enrolled. (bool, optional)

ipaclient_use_otp - Enforce the generation of a one time password to configure new and existing hosts. The enforcement on an existing host is not done if there is a working krb5.keytab on the host. If the generation of an otp is enforced for an existing host entry, then the host gets diabled and the containing keytab gets removed. (bool, optional)

ipaclient_allow_repair - Allow repair of already joined hosts. Contrary to ipaclient_force_join the host entry will not be changed on the server. (bool, optional)

ipaclient_kinit_attempts - Repeat the request for host Kerberos ticket X times if it fails. (int, optional)

ipaclient_no_ntp - Set to yes to not configure and enable NTP (bool, optional)

ipaclient_mkhomedir - Set to yes to configure PAM to create a users home directory if it does not exist. (string, optional)

Cluster Specific Variables

ipaclient_no_dns_lookup - Set to 'yes' to use groups.ipaserver in cluster environments as servers for the clients. This deactivates DNS lookup in krb5. (bool, optional, default: 'no')

ipareplica_servers - Manually override list of servers for example in a cluster environment on a per client basis. The list of servers is normally taken from from groups.ipaserver in cluster environments. (list of strings, optional)

Requirements

freeipa-server v4.6 or later
