I'm unable to get host checking to work. I have followed what I think are the correct steps but I still get "Access denied for this host" when I specify a server or the * wildcard for all servers.
The hostname command returns cadb5 so host lookups are working. Do you actually need a full blown DNS solution rather than host files to get this working?

The users account has the hostObject class and the host attribute:
