20 Chapter 2 Setting Up and Managing iChat Service
 General. Use to set host domains, SSL certificate, authentication method, and XMPP
server-to-server federation for iChat.
 Logging. Use to configure message log settings for iChat.
The following sections describe how to configure these settings, and a final section
tells you how to start iChat when you finish.
Configuring General Settings
You use the General settings pane in iChat to add host domains, choose an SSL
certificate and authentication method, and configure XMPP server-to-server federation
settings.
To configure iChat General settings:
1 Open Server Admin and connect to the server.
2 Click the triangle to the left of the server.
The list of services appears.
3 From the expanded Servers list, select iChat.
4 Click Settings, then click General.
5 Click the Add (+) button to add host domains.
The Host Domains list designates the domain names you want iChat to support.
Initially, the server host name is shown. You can add or remove other names that
resolve to the iChat service IP address such as aliases defined in DNS. When starting
iChat you must specify a DNS for the service.
Host domains are used to construct Jabber IDs, which identify iChat users. An example
of a Jabber ID is [email protected].
6 From the SSL Certificate pop-up menu, choose an SSL certificate.
The menu lists all SSL certificates that have been installed on the server.
To create or add certificates, choose Manage Certificates from the SSL Certificate pop-
up menu.
For more information about increasing server security, see Mac OS X Server Security
Configuration. Information about creating and managing server certificates can also be
found in Server Administration.
7 Choose the method of authentication from the Authentication pop-up menu.
Choose Standard if you want iChat to only accept password authentication.
Choose Kerberos if you want iChat to only accept Kerberos authentication.
Choose Any Method if you want iChat to accept password and Kerberos authentication.
8 To permit iChat to communicate with other XMPP-compliant chat servers, select
“Enable XMPP server-to-server federation.”
