This error...  <error code='403' type='auth'><forbidden xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/></error> ...looks like the XMPP notification server is not allowing the calendar server's XMPP account (or "JID") to create/configure pubsub nodes.  The XMPP notification server keeps a list of privileged JIDs in /Library/Preferences/com.apple.NotificationServer.plist.
First, check to see that calendar server is configured to use the "com.apple.notificationuser@<your hostname>" account by running this command in terminal:
sudo serveradmin settings calendar:Notifications:Services:XMPPNotifier:JID
You should see something like:
calendar:Notifications:Services:XMPPNotifier:JID = "[email protected]"
Next, see who is in the notification server's "privileged users" list via:
serveradmin settings notification:privilegedUsers
You should see something like:
notification:privilegedUsers:_array_index:0 = "_notification_user"
notification:privilegedUsers:_array_index:1 = "com.apple.notificationuser"
If you don't see "com.apple.notificationuser", you'll need to edit /Library/Preferences/com.apple.NotificationServer.plist and add it to the "privilegedUsers" array like:
  <key>privilegedUsers</key>
          <array>
     <string>_notification_user</string>
     <string>com.apple.notificationuser</string>
          </array>
Then I would recommend rebooting the server so that you are sure the notification server is restarted and re-reads the plist.
