After too many months of neglect, I have completely rewritten my Zend_Auth tutorial so that it is compatible with Zend Framework 1.10!
As an experiment, I have written it directly in HTML, rather than PDF as before and cover the login form along with the login controller code required to authenticate a user using a database table. For good measure, I've included logging out and a view helper to show how to access the logged in user's details.
The full source code is also available, if you don't want to type it in :)
I hope you find it useful.
