Pubsub and calendarserver usage?

Hi,

I am trying to use calendarserver.org’ s pubsub notification. Basically it send caldav notifications to XMPP. As stated here:

I have done

To get the calendar server to send push notifications, first set up an account within openfire that the calendar server will use to log in to XMPP with. Next, edit your calendar server .plist file and fill in the XMPP account information into the "Notifications > Services > XMPPNotifier section. In there you’ll want to set “Enabled” to “”, and fill in the “Host”, “Port”, “JID”, “Password”, and “ServiceAddress” values. “Host” is the XMPP server name, “Port” is 5222 unless you’ve changed that in openfire. “JID” should be set to the Jabber ID you set up for calendar server within openfire, e.g. “calendarserver@…”. For “ServiceAddress”, use “pubsub.” prepended to your “Host” name, e.g. “pubsub.example.com”. Restart calendar server and it should then connect to your openfire server. See calendar server’s error.log for any connection/authentication errors. You can watch all the XMPP traffic between calendar server and openfire by inserting this to your cale

ndar server .plist:

But i still can’t get updates thru that user. Is there anything do I have to do on openfire? I use 3.7.1 (just upgraded to the latest version)

For service address do I have to create a DNS record? Or can some one enlighten me about this concept?
