Yesterday we looked at setting up an Open Directory Master in OS X Mountain Lion 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. 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…

Setting Up an Open Directory Master in OS X Mountain Lion Server
Open Directory has never been so easy to setup for a basic environment as it is in OS X Mountain Lion Server. 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 Mountain Lion Server, but with Open Directory, it’s just too…

Man Pages
For those learning OS X or other Unixy based systems, and for those who have been using them for decades, man is one of the most important commands in our arsenal. The man command is short for manual and shows us how to use each command that has a man page, or a page that acts as an instruction manual for the command (or method). Another command, apropos, searches the whatis database for objects that match a string, or entry. For example, if you’d like to see a listing of all man pages that reference the word case, use the following command: apropos case Or use whatis in the place…

Setting Up Open Directory Replicas With Lion Server
In Lion Server, Open Directory can be managed in one of three ways: using the Server application the Server Admin application or using the command line utilities. Configuring Open Directory has never been easier than it is in the Server application, though. As we looked at in a previous article, setting up an Open Directory master should be done using the Server application. But setting up an Open Directory replica should be done using the Server Admin application. The Server Admin application is not installed when you buy OS X Server on the App Store and so it can be obtained here. But first (or while that’s downloading even), open…

Server.app and Open Directory Rebuilds in Lion
Server.app in Lion is a pretty good app for most tasks. But I find myself frequently doing things that I don’t think developers intended me to do. One such item is setting up and tearing down Open Directory to test various iterations of enabling a master. I frequently use slapconfig to destroyldapserver: slapconfig -destroyldapserver Doing so almost immediately allows me to demote an Open Directory master to a stand-alone server and then repromote the server to a master or replica for testing purposes. If you do this, then Open Directory cannot be set back up using Server.app. The fix is to use Server Admin to repromote your server back to…

Removing Old Replicas from OD
There are a number of instances when you cannot remove a replica from Open Directory using Server Admin. This can be due to a variety of reasons, but if you cannot remove the replica from Server Admin then try doing so using slapconfig. For example, if the replica has an IP of 10.10.10.10 then the command would be: slapconfig -removereplica 10.10.10.10
