According to RFC 3920, in this case, the server should return a
<conflict/> to the new connection.

From section 7 :

   Client binds a resource:

   <iq type='set' id='bind_2'>
     <bind xmlns='urn:ietf:params:xml:ns:xmpp-bind'>
       <resource>someresource</resource>
     </bind>
   </iq>

   Resource identifier is in use:

   <iq type='error' id='bind_2'>
     <bind xmlns='urn:ietf:params:xml:ns:xmpp-bind'>
       <resource>someresource</resource>
     </bind>
     <error type='cancel'>
       <conflict xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/>
     </error>
   </iq>

Note that the <conflict/> error is sent to the new resource and not
the currently connected one.

Vinod.
