Description

I'm trying to use OpenSSL::X509::Store#verify_callback= to ignore all error during certificate validation, which according to man SSL_CTX_set_verify should be possible:

If verify_callback always returns 1, the TLS/SSL handshake will not be
terminated with respect to verification failures and the connection will
be established.

However, when I try to use simplest possible callback satifying the condition
above

cert_store.verify_callback = lambda do |preverify_ok, store_ctx|
	true
end

ruby still throws exception about certificate being invalid:

$ ~/ruby_debug/bin/ruby server.rb 
Traceback (most recent call last):
	1: from server.rb:24:in `<main>'
server.rb:24:in `accept': SSL_accept returned=1 errno=0 state=error: certificate verify failed (self signed certificate) (OpenSSL::SSL::SSLError)

and client

$ ~/ruby_debug/bin/ruby client.rb 
Traceback (most recent call last):
	1: from client.rb:20:in `<main>'
client.rb:20:in `connect': SSL_connect returned=1 errno=0 state=SSLv3/TLS write finished: tlsv1 alert unknown ca (OpenSSL::SSL::SSLError)

Both server.rb and client.rb are attached.
