XEP-0136 and Vacuum-IM doesn't work

Hi.

I can’t imagine how to make this construction work:

–Openfire 3.9.3

–Percona DB

–Monitoring Service 1.4.2

–Vacuum IM

Recently i used old version of Ejabberd server and try features introduced in XEP-0136.

As result - Vacuum IM download all the history from server.

Now, when i’ll try to do the same trick with Openfire - it doesn’t work.


I tried to do some genius-debug with XML console and help of XEP-0136 documentation.

GET:

<iq type='get' id='pref1'> <pref xmlns='urn:xmpp:archive'/> </iq>

RESULT:

<iq type="error" id="pref1" to="****************************/Vacuum-IM">
<error type="cancel" code="501">

<feature-not-implemented xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/>

</error>

</iq>

What i’m doing wrong? Thx for any kind of response.

That’s real headache for me.
