Registered User

I am fiddling around with variations of this now.... However, I have a set of columns in the users table that govern various permissions over the DB, (e.g. can create categories, can edit items, can delete items, etc, etc). So I can't really break it down into either admin or users, as I want to assign each user fine grained permissions - this is what makes setting the cookie (and then getting the page to render accordingly) quite difficult. As you say, if you login as somebody else the cookie gets clobbered and the "old" session assumes the values stored in the "new" sessions cookie.

It also becomes complicated when reading in cookie values. Say i'm logged in as both a user and an admin, and I try to remove an entry as the user, if the admin cookie exists as well, isn't it going to be a pain to decipher what's going on? (Because the script will be saying "if admin cookie exists - allow, else disallow), but both cookies will exist?

I think as a workaround for now, I will have to stick to limiting the thing to a single session per IP address. It's kludgy but will work. I think that it's just as easy to log out, and then log back in as a user with appropriate priveledges to do whatever needs doing. I've also set up a series of cookies that are set to various crypt()ed values to stop a user trying to forge a cookie with elevated priveledges and everything seems pretty secure at the moment.

Let me know if you come up with anything more (or if I've got the wrong end of the stick) - I'm still open to ideas and am still hacking around.

Thanks again,

Cheers
ZB
