    Export data from Open Directory for migrating users and groups

    Before we have this conversation, I want to give you some bad news. Your passwords aren’t going to migrate. The good news is that you only do directory services migrations every decade or two. The better news is that I’m not actually sure you need a directory service in the traditional sense that you’ve built directory services. With Apple’s Enterprise Connect and Nomad, we no longer need to bind in order to get Kerberos functionality. With MCX long-dead(ish) you’re now better off doing policies through configuration profiles.  So where does that leave us? There are some options. On Prem Active Directory. I can setup Active Directory in about 10 minutes.…

    Before You Upgrade to macOS Server 5.4 on High Sierra (macOS 10.13)

    The latest version of the Apple Server app is out (macOS Server 5.4), and before you upgrade, there are a few points to review: As always, make a clone of your computer before upgrading. During the upgrade to High Sierra, if the operating system is running on a solid state drive, the drive will automatically upgrade to APFS. You cannot share APFS volumes over AFP, so if you’re running file services, make sure you’re aware of that. You can choose not to upgrade to APFS using the command line to upgrade a server. Even though the file sharing services are not in the Server app, you can still configure ACLs…

    OS X Server 5 Logs

    OS X running the Server app has a lot of scripts used for enabling services, setting states, changing hostnames and the like. Once upon a time there was a script for OS X Server called server setup. It was a beautiful but too simplistic kind of script. Today, much of that logic has been moved out into more granular scripts, kept in /Applications/Server.app/Contents/ServerRoot/System/Library/ServerSetup, used by the server to perform all kinds of tasks. These scripts are, like a lot of other things in OS X Server. Some of these include the configuration of amavisd, docecot and alerts. These scripts can also be used for migrating services and data. Sometimes the scripts…

    Promote An OS X Server To A Replica

    Previously, we looked at setting up an Open Directory Master in OS X Server. An Open Directory Replica keeps a copy of the Open Directory database available for users even when the Master goes offline. But it can also take a part of the load from the Open Directory Master and when using the new Locales feature, balance network traffic. To get started with an Open Directory Replica, first enable SSH, now disabled by default. If SSH is not enabled, you will not be able to create an Open Directory Replica. SSH is enabled on a server by opening the Server app, clicking on the name of the server and…

    Demoting An Open Directory Server In Yosemite Server

    The command to create and tear down an Open Directory environment is slapconfig. When you disable Open Directory from the Server app you aren’t actually removing users. To do so, you’d use slapconfig along with the -destroyldapserver. When run, you get a little insight into what’s happening behind the scenes. This results in the following: bash-3.2# slapconfig -destroyldapserver The logs are as follows: 2014-09-18 14:42:02 +0000 slapconfig -destroyldapserver 2014-09-18 14:42:02 +0000 CopyReplicaArray: ldap_search_ext_s failed 2014-09-18 14:42:02 +0000 Error retrieving replica array 2014-09-18 14:42:02 +0000 Deleting Cert Authority related data 2014-09-18 14:42:03 +0000 Removed directory at path /var/root/Library/Application Support/Certificate Authority/Take Control Books Open Directory Certification Authority. 2014-09-18 14:42:03 +0000 command: /usr/sbin/xscertadmin…

An Open Directory Replica keeps a copy of the Open Directory database available for users even when the Master goes offline. But it can also take a part of the load from the Open Directory Master and when using the new Locales feature, balance network traffic. To get started with an Open Directory Replica, first enable SSH, now disabled by default. Next, use the changeip to check the host name. While the Server app is cool, it caches stuff and I’ve seen it let things go threat shouldn’t be let go. Therefore, in order to make…

    Promote A Yosemite Open Directory Replica To A Master

    You’ve got Open Directory running and humming beautifully in OS X Server (Server 3.5 on OS X 10.10 Yosemite). You show up to work and the hard drive has died on that perfectly configured Open Directory Master. Luckily, you have a replica and you have an archive of your Master. You can restore or you can promote your Replica to a Master. What to do? Well, I can’t tell you what you should do, but I can tell you that Apple has planned for this. Here, we’re going to look at promoting that Replica to a Master. Because after all, hard drives fail. Let’s look at what all this looks…

    Configure Mavericks Server To Be An Open Directory Master

    Open Directory has never been so easy to setup for a basic environment as it is in OS X Mavericks Server (OS X 10.9, Server app 3). It’s also never been so annoyingly simple to use that to do anything cool requires a bunch of command line foo. No offense to the developers, but this whole idea that the screens that were being continually refined for a decade just need to be thrown out and started fresh seems to have led to a few babies thrown out along with them. Not often as I’m kinda’ digging most of the new config screens in OS X Mavericks Server, but with Open…
