[erlang-questions] erlang SSL client verification for self-signed certificates

Hallo!

I have a question, I try to check client certificate verification using
selfsigned server certificates.

I'll try to use it:

ssl:connect("localhost", 8443, [binary, {verify, verify_peer}, {cacertfile,
"cert.pem"}], 60000)
> {:error, {:tls_alert, 'bad certificate'}}

After tracing, I got:
public_key.pkix_path_validation/3 -> {error, {bad_cert, selfsigned_peer}}

If I try to exclude this error, by rewriting verification fun, which allow
this fun to be a valid, than all certificates are accepted. Is it possible
somehow to verify server self-signed certificate?
