MacOS Server Replacement #3 – Move OpenDirectory (LDAP) and DNS to FreeIPA on Fedora

As part of the migration of my MacOS Server to Linux the most tricky service to migrate is Apple’s OpenDirectory service. Although it is based on the open-source OpenLDAP project, Apple did customize things a lot, making it very tricky to move and block a real migration due to these closed-source customizations.  Instead of spending a lot of time on trying to figure out how to migrate OpenDirectory, I decided to start with a clean FreeIPA installation and migrate the users to that. Since I have been using MacOS Server’s OpenDirectory handled my  authentication for quite some time and ran in to issues before I learned that starting from scratch (and only migrating user information) isn’t that hard and in often the best approach.

As it is already quite long, this post focuses on how to configure FreeIPA on Fedora Core and migrating DNS and users. Integrating MacOS is covered on the FreeIPA WiKi and will be covered in a subsequent post including the integration with Apple’s Profile Server (the main component Apple seems to intend to support in the future). To aid with the configuration / setup I wrote a couple of scripts that are available from my Gitlab instance.

MacOS Server Replacement #2 – Migrating PostgreSQL

As part of the migration of my MacOS Server to Linux the next service to migrate is my PostgreSQL engine. Although PostgreSQL had already been hidden in MacOS Server for some time, it still was included (as internal services like ProfileManager and Calendar and Addressbook Server depend on it.  Despite it being hidden, I had still enabled it (manually) and hosted my PostgreSQL databases on my MacOS Server for ages. Despite migrations sometimes being a pain (i.e. not automatic) this worked well so far, including integrating it with the MacOS Server way of using transaction logs for offline backups. (so I will also have to look for a new way to do this). Continue reading “MacOS Server Replacement #2 – Migrating PostgreSQL”

MacOS Server Replacement #1 – Migrating MySQL to MariaDB

As part of the migration of my MacOS Server to Linux the first service to migrate is my MySQL 5.7 engine. Although MySQL is not part of MacOS Server anymore for a long time (and I had installed it separately), I will cover the migration here as 1) I still had it running on my MacOS Server and 2) the migration wasn’t smooth so decided to share my learnings here.

Apple totally strips MacOS Server

Today I noticed that there was a new update for MacOS Server that had quite a lengthy explaination:

As per Apple Knowledge Base article HT208312, the once great Apple Server product as this fall will be reduced to:

  1. Profile Manager
  2. Open Directory
  3. Xsan

The rationale of this is, according to Apple:

In fall 2018, Apple will stop bundling open source services such as Calendar Server, Contacts Server, the Mail Server, DNS, DHCP, VPN Server, and Websites with macOS Server. Customers can get these same services directly from open-source providers. This way, macOS Server customers can install the most secure and up-to-date services as soon as they’re available.

Signal Desktop stand-alone OS X Application

For quite some time I am an happy user of Open Whisper Systems’ Signal Messenger phone application as alternative to WhatsApp. The fact that this solution is open source and that the exchange of messages (and now also calls) is secure and that this can be verified by anyone are important and valuable. I use it on my phone but as I spend most of my time behind a laptop and still (call me old-fashioned) prefer a real keyboard over a touch screen I have been looking for a way to use it from my laptop as well.
