Cookbook Tutorials

Simple Login Tutorial (PDF) - Learn how to use interceptors in this simple login tutorial which builds on the "Quick Start" tutorial.

the User class fails in run-app since the constraints should be declared static "def constraints " should be "static def constraints" or similar (using 0.6rc1)
it's not obvious, for a first timer (I've only done the quick start) that the login page given should be saved to grails-app/views/user/login.gsp , it's logical once you know, but the tutorial could specify this.
within the new interceptor: you should exclude also the actions "login" and "doLogin", otherwise your redirect will loop
