We use an HTTP proxy (tinyproxy) on a dedicated machine to be able to reach legacy services from our GKE cluster with a static IP address. I'm aware that this is not the best solution, but the requirements are set by the target environment on which we have no control, and this solution works great for HTTP and SSH requests.
We now have the requirement to connect to an existing LDAP server, and in this case again do so from a static IP address. Is there a way to do this by sending requests to the LDAP server through the HTTP proxy?
