Using LWP with SSL and client certificates

Question

I'm porting an application from PHP/cURL to Perl and LWP::UserAgent. I need to do a POST request to a web server and provide a client certificate and key file. The PHP code I'm trying to replicate is this:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($ch, CURLOPT_SSLCERT, "/path/to/certificate.pem"); 
curl_setopt($ch, CURLOPT_SSLKEY, "/path/to/private.key"); 
curl_setopt($ch, CURLOPT_SSLKEYPASSWD, "secretpassword");

And here's my Perl code:

my $ua = LWP::UserAgent->new();
$ua->ssl_opts(
   SSL_verify_mode => 0,
   SSL_cert_file   => '/path/to/certificate.pem',
   SSL_key_file    => "/path/to/private.key",
   SSL_passwd_cb   => sub { return "secretpassword"; }  
);

The PHP code successfully connects to the server but the Perl code fails with:

SSL read error error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure

I can't figure out what I'm missing.
