Requirements

• The first master as well as the replicas must be configured with the appropriate upstream DNS servers in /etc/resolv.conf
• All Servers must be set up with the correct FQHN

Upstream Documentation

Please also see the examples on https://github.com/freeipa/ansible-freeipa

Usage

In a setup with an external DNS infrastructre, ensure that at least the primary master is white listed to allow nsupdates. This is required to automatically configure the required SRV entries before installing the replicas.

Preparations

Change the password for the vault file passwd.yml, the default password is "changeme". ansible-vault rekey passwd.yml. Edit the passwd.yml file and set some secure passwords for the ipa-admin and Directory Manager users. ansible-vault edit passwd.yml

The first two playbooks are installing the IPA Servers and does some basic configs, the later one is setting up the configuration stuff such as user- and hostgroups, hbac, sudoers, trust and so on.

The playbooks have a number prefix which indicates the sequence in which they should be run.

First Master Part I

The first playbook installs the software and creates a certficate signing request (CSR) which can be sent to an upstream CA to get signed. The resulting CSR will be fetched to files/-ipa.csr

ansible-playbook --ask-vault 01-setup-master.yml

First Master Part II

02-setup-master-part2.yml

This is the second part of the master setup. Please ensure that the Subordinate CA-cert is merged together with all upstream CA-certs. I.e.

cp ca.crt chain.crt
cat subca.crt >> chain.crt
cat ipa-ca.crt >> chain.crt
