A howto on howtoforge is in most cases written for a specific Linux distribution and version, in this case Ubuntu 9.10. If you like to write a guide for a different (later) ubuntu version on the same topic, then please start a new tutorial. If we would update the old one, then information on how to configure the setup on the old ubuntu version would get lost which might be useful for users as reference e.g. when they have to migrate a setup.
Please contact Falko e.g. by writing him a PM here in the forum if you like to reuse content from his tutorial.
