Can some one point me to a good way to implement permissions on a site. I would like a link that tells me how to implement good security on a user bases. What is the best way to set up a database to allow access based on per user and/or per type of user? I needs to scale fairly large. Ex. Admins can see things on the screen that normal users cannot, etc. I know this is vague. I know how to make logins and check theat against a DB, I want to know a decent way to make permissions on a element by element bases.
