Where do I get help with secure LDAP connection from Shibboleth IdP v 4.1.2

[Wiktor Kuśmierczyk]

I'm preparing Shibboleth IdP v 4.1.2 for operation as single sign on server, with Google Secure LDAP as identity catalogue.

How do I make it working using certficates. Exemplary config or manual is needed to see: how do i use certificate with key provided by Google.
