According to the XEP-0163 ( http://xmpp.org/extensions/xep-0163.html#support ) server is supposed to include this identity in our bare JID if PEP is supported:
<identity category='pubsub' type='pep'/>
but what I receive from my server (jabber.belnet.be) is
<identity category='pubsub' type='service'/>
I think this server is running ejabberd 2.1.3 but I'm not 100% sure of the exact version. I'll try to check with an admin if possible.
This bug is really annoying to us because telepathy-gabble used to rely on the server features to check if PEP was supported. This was wrong but ejabberd used to advertise this identity in the server features so we didn't notice this bug until now.
We are going to fix telepathy-gabble ( https://bugs.freedesktop.org/show_bug.cgi?id=28230 ) but that still won't work as ejabberd doesn't advertise the right identity.
