Hi everyone,
I've resolved the issue after i wrote above entry.
You need to configure local CA on one of your servers according to below link and then create necessary certificates with SHA256 hash algorithm (local CA also should have the same setting)

If you're working on Win 2012 server and still getting an error regarding Schannel SSP, you need to follow below SAP note in order to solve the issue.
2174821 - CCtr 7 - SSO does not work anymore since upgrade to SP7 and OS 2012
I hope this helps.
