I originally posted this at http://www.318.com/TechJournal Customizing the welcome message to new users of your iChat server is a fairly simple task. For this, we’ll look into the jabber configuration because jabber is the Open Source package that iChat Server is built on. When you first setup jabber the /etc/jabber directory will be created. Inside this folder will be a file called jabber.xml. If you open the jabber xml file and look for the “welcome†tag then anything between the "welcome" and"/welcome" will be the information that is shown in a welcome screen when a new user signs onto the iChat server. Before you edit the /etc/jaber/jabber.xml file make sure to back it…

Mac OS X Server 10.5: Troubleshooting CalDAV
I originally posted this at http://www.318.com/TechJournal So you installed your new server and you’re having a few problems. Let’s look at the common issues and a few simple fixes for them. iCal will not start, with log entries that it is unable to create a virtual host: Check your host name. iCal is going to need the host name to be correct in order to start.

Mac OS X Server 10.5: Self Updating Directory Entries
I originally posted this at http://www.318.com/TechJournal If you’re migrating to Leopard and Leopard Server then you’ve likely noticed the welcome addition of a new program in /Applications/Utilities called Directory. Directory allows users bound into an Open Directory environment to update LDAP records provided they have access to do so. Using LDAP ACLs it’s possible to give users access to update their own directory information using an LDAP directory browser such as Directory. When you open Directory you should see a listing of all of the directory information that has been created. From here you can create Shared Contacts, Groups, Locations and Resources. Each of these can be connected to a…
