Sessions / Var Tracking

Session Tracking / Var Tracking Theories I am interested in logging people in against a MySQL database, and then storing temporary session data about them that would include anonymity stats, permissions, and variable tracking from page to page in a MySQL Database. (As opposed to insecure POST/GET/Cookie methods). I have seen this before and the implementation I saw was relatively straight forward (The book "Core PHP Programming," [Orange Book of PHP] basically explains the method I saw. Is anyone out there using something drastically different? To the experienced: How do you authenticate and track people through your site? Do you foresee flaws (possible flaws) in your system? Does a perfect system exist?
