How to add an igniteuser (john@contoso.com) from gtalk/gmail

Hi OF team,

I am trying to federate Openfire with Gtalk, like S2S but not sure how this can be done. Can you please suggest me how to acheive this?

Please make a note that, i am not looking for IM-Gateway plugin solution. Rather, i am looking for some kind of S2S connect feature so that, i can add my colleague ("john@contoso.com") in Gtalk, when i login as "mouli@gmail.com".

Thanking you once again.

WIth regards,

Mouli.
