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:
[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:
- 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:
- 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:
[ipaclients]
ipaclient1.example.com
ipaclient2.example.com
[ipaservers]

[ipaclients:vars]

Variables
---------
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.
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.
