Tonight I am working on adding a flexible permissions system to my PHP application ‘Dataface’. I have a predisposition towards using PEAR classes where I can so naturally I decided to try LiveUser. Unfortunately the documentation is scarce, and all but to-the-point. I was, however impressed with this short article (http://jystewart.net/process/archives/2005/07/configuring-liveuser) that cuts to the chase on how to set up Live User. I recommend this one to anyone looking for User management in a PHP application.
