Reading php documentation about SSL_version, you'd better do nothing at all, just let libcurl decides.
Please, remove
<parameter key="be_simple.sso_auth.client.option.curlopt_sslversion.key">32</parameter>
and
<parameter key="be_simple.sso_auth.client.option.curlopt_sslversion.value">3</parameter>
Php doc quote : "Your best bet is to not set this and let it use the default. Setting it to 2 or 3 is very dangerous given the known vulnerabilities in SSLv2 and SSLv3."
