[jdev] Registering a new user

[Igor Urdenko]

Hello everybody.
I have a question about new user registration process.
What happens when Jabber client sends register packet like

<iq type='set' id='id_1'>
    <query xmlns='jabber:iq:register'>
        <username>NewUserName</username>
        <password>Password</password>
    </query>
</iq>

but user NewUserName already exists? What will server responce?
I test it with Merak Server but responce is always 'Error 403 Forbidden' -
is that common server responce? Because I was expecting something like

<iq type='error' id='id_1'>
    <query xmlns='jabber:iq:register'>
        <username>NewUserName</username>
    </query>
    <error code='...'>Already registered</error>
</iq>

What is correct?
Thank you.
