There are a couple of ways to create groups in macOS Server 5.4, running on High Sierra. The first is using the Server app, the second is using the Users & Groups System Preference pane and the third is using the command line. In this article we will look at creating groups in the directory service with the Server app. Once a server has been an Open Directory Master all user and group accounts created will be in the Local Network Group when created in Server app. Before that, all user and group objects are stored locally when created in Server app. Once promoted to an Open Directory server, groups are created in the…

Xsan Command Line Options In High Sierra
Let’s start out with what’s actually available in the Server Admin CLI: serveradmin. The serveradmin command, followed by settings, followed by san shows a few pieces of information: /Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin settings san The results would be similar to: san:computers = _empty_array san:primaryController = "95C99FB1-80F2-5016-B9C3-BE3916E6E5DC" san:ownerEmail = "krypted@me.com" san:sanName = "krypted" san:desiredSearchPolicy:_array_index:0 = "" san:serialNumbers = _empty_array san:dsType = 0 san:ownerName = "Charles Edge" san:managePrivateNetwork = yes san:metadataNetwork = "10.0.0.0/24" san:numberOfFibreChannelPorts = 2 san:role = "CONTROLLER" Here, we see the metadata network, the GUID of the primary (active) MDC, the name of the SAN, an array of serial numbers (if applicable – rarely encountered these days), the owner info plugged in earlier…

Setup An Open Directory Master In macOS Server 5.4 On High Sierra (10.13)
Open Directory has never been this easy to setup for a basic environment as it is in macOS Server 5.4 (for macOS 10.13 running on High Sierra). As with almost any previous version of macOS Server and Open Directory, once you’ve installed the Server app, run the changeip command along with the -checkhostname option to verify that the IP, DNS and hostname match. If (and only if as it will fail if you try anyway) you get an indication of “Success.” I know, I know, you’ve been told that you didn’t have to do this kind of command line stuff any more… But really, you should – and if you don’t…

Setup The Calendar Service In macOS Server 5.4 for High Sierra
Configuring Calendar Server in macOS Server 5.4 (running on High Sierra) is a fairly simple and straight forward process.

Using The Messages Service In macOS Server 5.4 On High Sierra
Getting started with Messages Server couldn’t really be easier. Messages Server in the macOS Server 5.4 version of the Server app uses the open source jabber project as the back-end code base. The jabber binary is located at /Applications/Server.app/Contents/ServerRoot/private/var/jabberd directory and the autobuddy binary is at /Applications/Server.app/Contents/ServerRoot/usr/bin/jabber_autobuddy. The actual jabberd binary is also stored at /Applications/Server.app/Contents/ServerRoot/usr/libexec/jabberd, where there are a couple of perl scripts used to migrate the service between various versions as well. Setting up the Messages service is simple. Open the Server app and click on Messages in the Server app sidebar.  Click on the Edit… button for the Permissions. Here, define which users and interfaces are allowed to…

Demote Open Directory Servers Using The Command Line in macOS 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# sudo slapconfig -destroyldapserver The logs are as follows: 2017-09-09 20:59:31 +0000 slapconfig -destroyldapserver 2017-09-09 20:59:31 +0000 Deleting Cert Authority related data 2017-09-09 20:59:31 +0000 Removed directory at path /var/root/Library/Application Support/Certificate Authority/krypted Open Directory Certificate Authority. 2017-09-09 20:59:31 +0000 command: /usr/sbin/xscertadmin add –reason 5 –issuer krypted Open Directory Certificate Authority –serial 1339109282 2017-09-09 20:59:51 +0000…
