title: Tapestry 5 user authentication
body: <p>I was following the very slim tutorial on the Tapestry website for Tapestry 5 and was introduced to very basic database interactions but not how to do user authentication.  Where do I go for more comprehensive guidance in tapestry 5?  I went to the tapestry wiki (http://wiki.apache.org/tapestry/Tapestry5HowTos) but I wasn't really looking for a bunch of how-to's.  Do you know of any good sources?</p>
