User should not able chat to user that outside the Group

Hi

I installed the open fire recently and Its working fine, But i have few issue

  • Contact list is not auto pull i need to add the contacts manually
  • Suppose there are three Groups A.B and C. I want Users from A group cant able to chat to user from Group B vice versa. But user from Group C can chat with users from Group A and B
  1. create groups, add users to groups, enable sharing in the groups’ settings

  2. you can try Packet Filter plugin and create rules blocking message packets between group A and group B.
