<p>The host MUST perform the remove based on the 'from' address of the IQ set, usually matching based on bare JID (<user@domain>). If the entity cancels its registration with a server (not a service), the server SHOULD then return a <not-authorized/> stream error and terminate all active sessions for the entity. If the server is an instant messaging and presence server that conforms to &rfc3921;, the server SHOULD also cancel all existing presence subscriptions related to that entity (as stored in the entity's roster).</p>
|
||||
<p>Several error cases are possible:</p>
|
||||
<p>There are two scenarios:</p>
|
||||
<ol>
|
||||
<li><p>If the entity cancels its registration with its "home" server (i.e., the server at which it has maintained its XMPP account), then the entity SHOULD NOT include a 'from' or 'to' address in the remove request the server SHOULD then return a <not-authorized/> stream error and terminate all active sessions for the entity. The server SHOULD perform the remove based on the bare JID (&BAREJID;) associated with the current session or connection over which it received the remove request. If the server is an instant messaging and presence server that conforms to &rfc3921;, the server SHOULD also cancel all existing presence subscriptions related to that entity (as stored in the entity's roster).</p></li>
|
||||
<li><p>If the entity cancels its registration with a service other than its home server, its home server MUST stamp a 'from' address on the remove request, which in accordance with <cite>XMPP Core</cite> will be the entity's full JID (&FULLJID;). The service MUST perform the remove based on the bare JID (&BAREJID;) portion of the 'from' address.</p></li>
