Hi @sgardj_2482 , ProGet's Integrated Web Server already supports Windows Integrated Authentication (WIA). Actually it supports WIA better than better than IIS in that only the Web UI and supported feeds (or ones you configure) will do the WIA challenge. Behind the scenes, the Integrated Web Server (IWS) uses Kestrel unless you're doing so-called "port sharing", which would be having two web applications sharing the same port. That's becoming less and less common, and isn't something Microsoft recommends anymore. If you bind to a host name in IWS (i.e. port sharing), then the operating-system level HTTP.SYS component is used. That is much less flexible with WIA and every request must be authenticated. Which means it'll never work with Docker, npm, etc. So it's not recommended. Thanks, Alana

Ok thanks for the explanation.
