(See the best response by Kaiochao.)
Code:
turf/hiddenwalls
    leafwall
        Enter(mob/M)
            if(M.village != "Leaf")
                var/entry = 0
                for(var/obj/inventory/leafpass in M.contents)
                    entry = 1
                if(entry == 1)
                    return 1
                else
                    M << "You can't go in the leaf village without a passport!"
                    return 0
            else
                return 1


Problem description:Anyone can go through the wall, even people without a passport.

Are you getting the message saying you can't pass? Also, there's no guarantee in that code that M will be a mob, you'll want an ismob() check and probably a client check if you only want players being checked.

You can check for the pass in their inventory without a loop as well.
var/obj/inventory/leafpass/has_pass = locate() in M.contents
if(has_pass) // They have it.
    // Do stuff


You should also be sure you're NOT in the Leaf village.

The problem is that he's not actually looking for a leafpass; he's looking for any /obj/inventory in M.

Good catch.
