I have the following problem, I have a “group A” of users and a “group B” with other users.
If I share the contacts from group A with group B, they can see each other, but I want group A not to see who is logging along with him in the same group, just who is in group B. And group B You can see who is logged in with him and is not in group A.
I use Spark 2.8.3 as a client and a version of my Firefox OpenFire is 4.1.5.
Are there any plugins to manage this communication?
