Add user to shared group (XEP-0140)

We are creating custom XMPP-client and are using OpenFire server 3.9.3. Question is: does OpenFire fully support standart XEP-0140: Shared Groups (http://xmpp.org/extensions/xep-0140.html) or a newer standart XEP-0144: Roster Item Exchange (http://xmpp.org/extensions/xep-0144.html)?

We are able to programmatically create new users using XEP-0133 (http://xmpp.org/extensions/xep-0133.html#add-user), but we are unable to add them to a shared group using XEP-0140 (http://xmpp.org/extensions/xep-0140.html#add).

Used XMPP-query example:

<iqtype='set'
    from='bofh@example.com/daygig'
    to='pubsub.example.com'
    id='sub1'>
<pubsubxmlns='http://jabber.org/protocol/pubsub'>
    <entitiesnode='groups/Marketing/Europe'>
      <entityjid='alice@example.com'
              affiliation='none'
              subscription='subscribed'/>
    </entities>
</pubsub>
</iq>

For this server returns:

<bad-request xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"></bad-request>

</error>

Standart XEP-0144 doesn't work either, or it even can't be used for this purpose...

Any ideas / suggestions?
