users match list criteria and vendor identification

Hi I am trying to find a list of the criteria you can use in the users file on the match line, I came across a lengthy list/table earlier but can't seem to find it again. I have looked at the attributes RFC, but I'm looking more for something that will list things like Group-Name, Auth-Type, and more importantly the other possible criteria I can include there. One of the things I am curious to see is if there is a Vendor-ID attribute, does anyone know if there is? Any help is greatly appreciated.
