This is a a problem in your DNS?? If you don't want this check, then you should specificy SkipVerify. But reverse lookup *ought to be possible*, or am I misunderstanding your point?
I think you miss the point. I add the hosts entry on the /client/ side. The server is ignoring the fact that that IP actually resolves to something else and blindly trusts client that the FQDN for the client is foobar.lon4.fastsearch.net
At some point the during the conversation the client is saying "I think I'm called foobar.lon4.fastsearch.net" and the server believes this.
On 2.0.3 this can be considered to be a DoS attack, as it actually coredumps cfservd.
