Get SAP Logon Ticket in C# from web application on IIS running on different server than NetWeaver

Our company uses SSO to netweaver. I have a .net c# web application that is running on a different IIS server than netweaver that has to somehow programmatically get a SAP Logon Ticket string. I've downloaded the SAP .NET Conector 3.0 (2 DLLs) off of github, but don't see any methods to get a Logon Ticket.

Please let me know how I can accomplish this. Thanks!
