Latest update causing failed authentication

The latest update, 1.9.7, results in CAS Authentication Failed! message. We are running WordPress behind an F5 load-balancer with SSL-offload. We have X-Forwarded-Proto and X-Forwarded-Port defined on incoming server traffic, which causes the new code for “nginx behind AWS loadbalancer” to fire. In this new block (classes/wp_cassify_utils.php), the protocol is not set for $current_url making the validate call fail as it does not match a valid service identifier. Below is a diff of the changes I made to work for our environment. Perhaps this change will work for AWS as well?

Thanks again for the great plugin.
