Ldap with Jumpcloud

[bizops]

Hi there, 

I'm trying to understand what version of TLS is used for the 'Simple' authentication type, does anyone have an idea? 
Hopefully its not TLS v1.1 ? 

many thanks

It is TLS v1.2

echo -n | openssl s_client -connect ldap.jumpcloud.com:636 -showcerts

lots of output
