This is very odd. What SSL library are you using for the network 
tests ? Just run "bbtest-net --version" and you should get:

  bbtest-net version 4.2.0
  SSL library : OpenSSL 0.9.8a 11 Oct 2005
  LDAP library: OpenLDAP 20130

It sounds as if the SSL library is attempting to verify the 
authenticity of the SSL certificate from your server. But I've never
heard of it doing this by default. So I'd like to know which version
of OpenSSL you are using, so I can see if there's a configuration
setting that Hobbit can tweak to disable this.
