Auto subscribe publishers

Hi,

In XEP-0060 this is metioned:

A service MUST allow owners and publishers to subscribe to a node, and to retrieve items from a node even if they are not subscribed. A service MAY auto-subscribe owners and publishers if they are not already subscribed,

How do I enable this auto subscribe to publishers in ejabberd? I want to keep the subscription access as authorize but owners and publishers are automatically subscribed. Others need to be authorized.

Is this implemented in ejabberd?
