ipaclient role
==============
Description
-----------
This role allows to join hosts as clients to an IPA domain. 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:
```ini
[ipaclients]
ipaclient1.example.com
ipaclient2.example.com
[ipaclients:vars]
ipaadmin_principal=admin
```
Example playbook to setup the IPA client(s) using principal from inventory file and password from an [Ansible Vault](http://docs.ansible.com/ansible/latest/playbooks_vault.html) file:
```yaml
- name: Playbook to configure IPA clients with username/password
hosts: ipaclients
become: true
vars_files:
- playbook_sensitive_data.yml
roles:
- role: ipaclient
state: present
```
Example playbook to unconfigure the IPA client(s) using principal and password from inventory file:
```yaml
- name: Playbook to unconfigure IPA clients
hosts: ipaclients
become: true
roles:
- role: ipaclient
state: absent
```
Example inventory file with fixed servers, principal, password and domain:
```ini
[ipaclients]
ipaclient1.example.com
ipaclient2.example.com
[ipaservers]
ipaserver.example.com
[ipaclients:vars]
ipaclient_domain=example.com
ipaadmin_principal=admin
ipaadmin_password=MySecretPassword123
```
Example playbook to setup the IPA client(s) using principal and password from inventory file:
```yaml
- name: Playbook to configure IPA clients with username/password
hosts: ipaclients
become: true
roles:
- role: ipaclient
state: present
```
Variables
---------
### `ipaclients`
The mandatory `ipaclients` group is a list of the names of the IPA clients in FQDN form. All these clients will be installed or configured using the playbook.
### `ipaclient_domain`
The optional `ipaclient_domain` variable sets the DNS domain that will be used for client installation. Usually the DNS domain is a lower-cased name of the Kerberos realm.
If `ipaclient_domain` is not set, then it will be generated from the domain part of the first entry from the `ipaservers` FQDN group if the group is defined and contains at least one entry. If `ipaservers` is not defined, then the domain will be tried to gather using DNS autodiscovery. `ipaclient_domain` needs to be set if the primary DNS domain is different from domain part of the server FQDN.
### `ipaclient_realm`
The optional `ipaclient_realm` sets the Kerberos realm that will be used for client installation. Usually the Kerberos realm is an upper-cased name of the DNS domain.
If `ipaclient_realm` is not set, then it will be generated from `ipaclient_domain` if this is set. If both are not set, then this
### `ipaclient_keytab`
The optional `ipaclient_keytab` contains the path of a backup host keytab from a previous enrollment.
### `ipaclient_force_join`
The `ipaclient_force_join` bool value defines if an already enrolled host can join again. `ipaclient_force_join` defaults to `no`.
### `ipaclient_use_otp`
The `ipaclient_use_otp` bool value defines if a one-time password will be generated to join a new or existing host. `ipaclient_use_otp` defaults to `no`.
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.
### `ipaclient_allow_repair`
The `ipaclient_allow_repair` bool value defines if an already joined or partly set-up client can be repaired. `ipaclient_allow_repair` defaults to `no`.
Contrary to `ipaclient_force_join=yes` the host entry will not be changed on the server.
### `ipaclient_kinit_attempts`
The optional `ipaclient_kinit_attempts` defines the number of tries to repeat the request for a failed host Kerberos ticket. `ipaclient_kinit_attempts` defaults to 3.
### `ipaclient_no_ntp`
The `ipaclient_no_ntp` bool value defines if NTP will not be configured and enabled. `ipaclient_no_ntp` defaults to `no`.
### `ipaclient_mkhomedir`
The `ipaclient_mkhomedir` bool value defines if PAM will be configured to create a users home directory if it does not exist. `ipaclient_mkhomedir` defaults to `no`.
Server Variables
----------------
### `ipaservers`
The optional `ipaservers` group is a list of the IPA server full qualified host names. In a topology with a chain of servers and replicas, it is important to use the right server or replica as the server for the client. If there is a need to overwrite the setting for a client in the `ipaclients` group, please use the list `ipaclient_servers` explained below.
If no `ipaservers` group is defined than the installation preparation step will try to use DNS autodiscovery to identify the the IPA server using DNS txt records.
### `ipaadmin_keytab`
The `ipaadmin_keytab` variable enables the use of an admin keytab as an alternativce authentication method. The variable needs to contain the local path to the keytab file. If `ipaadmin_keytab` is used, then `ipaadmin_password` does not need to be set.
### `ipaadmin_principal`
The optional `ipaadmin_principal` variable only needs to be set if the name of the Kerberos admin principal is not "admin". If `ipaadmin_principal` is not set it will be set internally to "admin".
### `ipaadmin_password`
The `ipaadmin_password` variable contains the Kerberos password of the Kerberos admin principal. If `ipaadmin_keytab` is used, then `ipaadmin_password` does not need to be set.
Topology Variables
------------------
These variables can be used to define or change how clients are arranged within a cluster for example.
### `ipaclient_no_dns_lookup`
The `ipaclient_no_dns_lookup` bool value defines if the `ipaservers` group will be used as servers for the clients automatically. If enabled this deactivates DNS lookup in Kerberos in client installations. `ipaclient_no_dns_lookup` defauults to `no`.
### `ipaclient_servers`
The optional `ipaclient_servers` varaible can be used to manually override list of servers on a per client basis. The list of servers is normally taken from from `ipaservers` group.
Requirements
------------
freeipa-client v4.4 or later

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.

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