I want to disable for user possibility to add new user except from his group. And i want to configure the openfire server if it’s possible
there is a “Subscription” plugin which allows to reject subscription requests. Anyhow it’s still possible to start a direct chat with a random user.
So maybe the “Packet Filter” is the plugin you want to use.
You may download the plugins within Openfire (recommended way) or here: http://www.igniterealtime.org/projects/openfire/plugins.jsp
