How to subscribe to gateway transports without having an account?

Dear Support. I’‘m wondered is that possible to subscribe to AIM/ICQ/MSN transports ran on openfire server from anohter jabber account (e.g. GTalk). When I’‘m trying to do so, I’'m receiving:


Your registration was denied due to your account not existing on the same server as the transport.

I’'ve anonymous login enabled and ICQ transport has “All users can register” permission set. Debug output does not help either.

Please, advice.
