Ansible Role freeipa_server

This role installs and configures FreeIPA as a server.

Ideally, the FreeIPA should be installed on a separate server. If that is not possible, you could group it with DNS and NTP on an infrastructure server. As a last resort you can install it on the central firewall / gateway server.

Mandatory Requirements

• At least 2 GB RAM are required.

• The IPA installer is quite picky about the DNS configuration. The following checks are done by installer:

  • The hostname cannot be localhost or localhost6.

  • The hostname must be fully-qualified (server.ipa.test). Use two-level domain names. Otherwise you’ll get error messages like Invalid realm name: single label realms are not supported.

  • The hostname must be resolvable.

  • The reverse lookup of the FreeIPA IP server address must match the hostname of the FreeIPA server. Otherwise you’ll get error messages like In unattended mode you need to provide at least -r, -p and -a options or The host name "ipa.example" does not match the value "myipa" obtained by reverse lookup on IP address 192.102.0.106.

  • If neither the domain nor the realm being set, you’ll get error messages like In unattended mode you need to provide at least -r, -p and -a options.

• Do not use an existing domain or hostname unless you own the domain. It’s a common mistake to use example.com. We recommend to use a reserved top level domain from RFC2606 for private test installations, e.g. ipa.test.

• Install the ansible-freeipa Ansible Collection on the Ansible control node. This can be done by calling ansible-galaxy collection install freeipa.ansible_freeipa.
