Setting Up iChat on Virtually Hosted Domains
iChat requires that your host have a host name to be used as the Jabber realm by the iChat server that is resolvable using DNS. This host name is used as the Jabber realm by the iChat server, and clients use this realm to connect to the service.
Clients use a Jabber Identifier (JID) to authenticate and interact with the server. The JID is in the format <user>@<realm> (for example, chatuser@chatserver.example.com). In this example, your iChat service should be configured to host the realm chatserver.example.com.
DNS resolution directs clients to your server when they resolve that host name. To support multiple realms, DNS should be configured appropriately. For more information, see Network Services Administration.
To configure iChat on a virtually hosted domain:
1Open Server Admin and connect to the server.
2Click the triangle to the left of the server. The list of services appears.
3From the expanded Servers list, select iChat.
4Click Settings, then click General.
5Change the realms served by iChat by adding a virtual domain to the Host Domains list.
Domains that are added will be supported as Jabber realms.
6Click Save and restart iChat if necessary.
