Thanks Alan, 

That's what I thought. I'll trace this back to our original source and have them check what's going on. 

Thanks for the confirmation :-)

      Nope.  I haven't seen it, and it's not in any standard.

      Only if you go out of your way to create a vendor dictionary with vendor ID 0, and then an attribute 0, and then manually add it to the configuration.
      If that attribute is coming from a NAS, then the NAS is broken.
      FreeRADIUS may make mistakes internally, it doesn't create bad RADIUS packets.
