Also, another thing is that a lot of what I was trying to do was not
only add user classes, but also restrict users from accessing my server
unless they were in the wheel group.

Got that done with /etc/login.access by adding:

- -ALL except wheel:ALL

Now since I mentioned it though I was wondering, does this create issues
for secondary daemon accounts (www, mysql, etc)?
