On the openfire-forum and on a lot of others is this the subject of many threads, however it almost works out of the box.

I'm running 3 domains which all like jabber support. Lazy as I am, I just want to maintain one jabber-server instance. All 3 domains are being authenticated on the same LDAP-server.

Openfire version: 3.3.3

Result is that all users of all domains are able to login and chat with each other. Users of the not default domain are also able to use the groupchats. But not everything is ok, there are also some issues:

Users of the not default domain:

• aren't listed
• show up as member of the default domain
• Not only show up as those, but for access lists you have to use the default domain. So this could give a user conflict
