how to configure ejabberd server so others can get online status, no matter in roster/friend or not (Web client is SMACK)?

Hi All,

We are using ejabberd as XMPP server, and in web client using SMACK.

In the web site, we list all users, and we WANT TO SHOW user online/offline status no matter who are your friends or not.

Any one can help out?

Thanks a lot.
