OK - when host machines connect to Samba and the 'hosts allow'
and 'hosts deny' options are present, Samba needs to determine
the DNS name to work out whether to allow the connection.  If the
host does not have a reverse IP then it is automatically rejected
as Samba cannot determine whether to allow or deny the
connection.  This is because the code is based on the tcp wrapper
code and netbios names are too easy to spoof.

Er, I don't think it is actually documented anywhere.  )-:
