Just found this thread, and everything was very useful to me, thanks!

I wanted to added my "solution", which is a variation on the previous ones, in case it helps someone else.

Adding

$ENV{PERL_LWP_SSL_VERIFY_HOSTNAME} = 0;

is definitely key. However, this causes a big warning to come out of IO::Socket::SLL:

*******************************************************************
 Using the default of SSL_verify_mode of SSL_VERIFY_NONE for client
 is deprecated! Please set SSL_verify_mode to SSL_VERIFY_PEER
 together with SSL_ca_file|SSL_ca_path for verification.
 If you really don't want to verify the certificate and keep the
 connection open to Man-In-The-Middle attacks please set
 SSL_verify_mode explicitly to SSL_VERIFY_NONE in your application.
*******************************************************************

The way to get rid of that warning was to add these lines:

use IO::Socket::SSL;
IO::Socket::SSL::set_defaults(SSL_verify_mode => "SSL_VERIFY_NONE");

In addition to the original $ENV{PERL_LWP_SSL_VERIFY_HOSTNAME}, that should work no matter what client you're using (LWP::UserAgent, RPC::XML::Client, SOAP::Lite, etc.).

Hope that helps someone else!
