This list specifies the names of hosts which are to have read
access to files, regardless of the owner of the file. This effectively
gives root users on connecting hosts privileges to non-root owned
files on the server, but not vice-versa, similar to the NFS root mapping,
except that there is no question of a client being able to modify files
on the server. Caution: cfservd trusts the DNS service, so be aware that
cache poisoning attacks are a possible way of bypassing access controls.
As of version 2.0.4: Once a verified host address has been identified with a functioning
public/private key authentication, the IP address is added to the SkipVerify
list, so that time is not wasted in verifying reverse lookups, when the
identify can be verified more efficiently and securely by a key mechanism.
