18 Chapter 2 Setting Up and Managing iChat Service
Setup Overview
Here is an overview of the steps for setting up iChat service:
Step 1: Configure and start Open Directory
iChat uses Open Directory to authenticate users and must be configured before setting
up iChat. See “Configuring and Starting Open Directory” on page 18.
Step 2: (Optional) Set up Firewall service
If you are using a firewall, iChat requires specific ports to be open for iChat features to
function. See “Opening Firewall Ports for iChat Service” on page 19.
For more information about Firewall service, see Network Services Administration.
Step 3: Turn iChat service on
Before you configure iChat, turn it on. See “Turning iChat Service On” on page 19.
Step 4: Configure iChat General settings
Configure the General settings to add host domains, select an SSL certificate, choose
your authentication method, and enable XMPP server-to-server federation. See
“Configuring General Settings” on page 20.
Step 5: Configure iChat Logging settings
Use Logging settings to specify where to archive the iChat message logs. See
“Configuring Logging Settings” on page 21.
Step 6: Start iChat
Start iChat on the server using Server Admin. See “Starting iChat” on page 21.
Configuring and Starting Open Directory
iChat uses Open Directory to authenticate users and service access control lists (SACLs)
to verify that users are authorized to use iChat. For more information about configuring
Open Directory, see Open Directory Administration.
Before you can use iChat:
 You must be defined in the Open Directory search path of that server
 You must be authorized to use iChat service on that server
After you log in to iChat, you can chat with any other users who have access to the
same iChat server or who are reachable using server-to-server federation, if it is
enabled.
For more information about search paths and iChat service authentication, see “Setting
Access Control for iChat” on page 22.
