2 AD Domains, 2 Openfire Servers, Roster Populate?

Hi,

I have 2 AD Domains with an Openfire server for each. I also have S2S setup and working. How can I populate the rosters of users in Domain2 with contacts from Domain1 and vice versa? Is it even possible?

If it helps, there is a 2 way trust between the domains.

Thanks!!!
