Assist with STUNNEL Configruation

I need assistance with either setting up STunnel on my server and my clients server. I just need the correct configuration for everything to function per below: 1. I will have STunnel client on 5+ customer machines, that will need to make "localhost:389" available to me. 2. All STunnel clients will connect to my STunnel Server via "MY-PUBLIC-DOMAIN:443" and need to authenticate certificate or something 3. Each client will be assigned a local port on my STunnel Server (ex. 1001,1002,1003,etc) 4. Another server on my network will send LDAP requests to the STunnel Server via these custom ports, and the requests need to be securely sent back through the tunnel to each clients LDAP server. The usage example above has been tested using [login to view URL] however I do not want to proxy through another network or service. The server component will exist only on my network.
