[JDEV] Updating registered user information

[Reinaldo Pires]

Hi!
I coun't find any example on how to update personal info of a registered
user.
For exemple, how can I change the password of a registered user??
I read in the docs that sending

<iq type="set"  id="1001" to="jabber.myserver.com">
 <query xmlns="jabber:iq:register">
   <username>test at myserver.com</username><password>test2</password>
   <key>5c2d3f34d3d1688942cadba68b0494d8dc048022</key>
 </query>
</iq>


to the server and if he user is already registered, his info would be
updated...
But this doesn't work ...
What am I missing? Does it have any undocumented flag like <update/> or
something like that??


Thank you for your help!
